Hey Wayne, in their case they would have had a much longer uphill run coming back than going. Lowering the tent makes a difference but exactly how much is impossible to say without identical tracks and test conditions. Still, 2.4 miles per gallon on a longer uphill run is significant.
While I agree that the mileage is affected, I wanted to say that using a different route may have messed up your numbers. For example, in my A4, when I drive South to San Diego from Orange County, I am at around 33.5 MPG. Coming back North, my mileage actually drops about 1.5 MPG. This has happened consistently for several years. Going East vs. West can also affect your mileage due to wind and elevation changes. Thanks for the great work!
Hey guys, do you know if there was any major elevation changes from the trip there compared to the trip back? e.g if you are travelling uphill the entire way there, the way back will be more efficient too. That is probably getting too specific but the results already speak for themselves
That was a great video. I am super down to see more videos on these edge case type of situations that most people would gloss over. Another good thing to test are the effects of tires. I have definitely seen people put their AT tires in the bed on their way to a trail in order to save fuel economy and wear. Keep it coming!
I enjoy experiment contents like this. I live in Salt lake City area and have taken countless trip (50+) to StG in last 8 years. I have always found that driving from SLC to STG I get 5-10% better MPG than driving from StG to SLC. It's combination of SLC being higher elevation and typical wind direction faced as headwind seems to be more common when coming back from StG. I am confident that if two trip loops were taken under similar condition, where one loop was done with Roofnest up above the roof line and second loop with below the roof line, the % of MPG will be even higher on the below the roof line setup what was found here.
To do this truly scientifically you should compare same direction, same day, same driving style, but I’m sure you know that and I know that’s more time consuming to make, whereas this you could make as part of your trip to an event. And I appreciate it. Vids like these are really helpful. Makes you think about some things you might not otherwise. Bet that side by side day was fun- looking forward to vid.
I sure would like to see fuel numbers for an F-150 with it's 3.5 engine and transmission over that same trip,.. I'd almost bet that the Chev / 5.3 is the fuel economy leader. Thanks for this Gentlemen!
It would be interesting to see how some incremental height adjustments affected fuel mileage. I would expect that letting the tent protrude a couple of inches above would not hurt mileage and return some rear visibility.
Great vid of what we suspected. Nice to see verification. Lower does make it hard to get to the front of the bed, more so on longer beds and older, human, bodies. Always trade offs
You 2 make a good team. Lot of editing time in the office these days to put this so far behind that actual trip. Same direction/miles with the tent in 2 different positions and 1 trip in the same direction with no tent at all would have been a more comparable test. But for the purpose of giving you something to do on the trip, it proves to help MPG.(no surprise)
The prevailing wind blows west to east, so going there with the box above the roof line you were also heading into the wind which could cause some of the difference too,
You have to make the full trip, both ways with the tent in each position else you will reach the wrong conclusion. Travelling east to west almost is always a different change in elevation then west to east. Sorry guys, I love your videos, but you need to redo this test.
I agree. Set it low and go to Utah. Set it high back to Colorado. Then crunch the #s. Also were they leadfooting it at certain times vs casual drive. Many many variables.
@@awesomexistence It doesn't matter, whether or not the work is performed rapidly or over time, it requires the same amount of energy to do the same amount of work. So moving an object of the same mass from one elevation to another requires the same amount of energy if it is done over 10 seconds or 6 hours. So the elevation changes depending on the direction they go, do matter for MPGs.
Have you considered doing an MPG comparison between a truck equipped with a rooftop tent that sits above the cab versus no rooftop tent while towing a small camping trailer like the Colorado Teardrops Summit model?
I average 19-21 70%, highway In my Trailboss. But most important the highway speed limit is 90kmh or 55mph. We do have some highways that are 70mph and the mileage drops to 17-18.
I've made two round trips from Buffalo New York to Vero Beach Florida. To use my cruise control every chance I get. I don't know why but I've always gotten close to 2 mi per gallon better going to Florida than coming back to New York both times.
I have an old Crown Victoria police car and used to make a similar trip a few times a year to visit relatives. It takes nearly 5 tankfuls of gas each way or about 9 total round trip. I have found that the portion of the trip between Fl and N.C. I get better than usual gas mileage, with slightly better results South to North. Myself? I attribute it to 2 things: a difference in the gasoline formulations (I use the same brand nearly the whole trip) and the fact that Georgia and the Carolinas are flatter than Virginia and Pennsylvania.
Case, I have a few questions. What speed were you driving at on the interstate? Is St. George, UT a nice place to visit? Is the roof top tent easily removable from the truck? Have you ever used the roof top tent? Do you like the setup? Thanks.
Watching this now as just got my 2022 model. But, would adding the air deflector in front help with mileage when RTT is above roof height on the truck bed? I was thinking of keeping it below the roof height for the reason to avoid blocking the RVMirror camera and of course for better mileage.
This instance is really pretty obvious, but sometimes what you think will be better actually isn't. I would like to see the same test on a truck with the tailgate up and one down. I remember seeing a truck run at Bonneville that had a tonneau cover that only covered the back half of the bed because their testing showed it was more aerodynamic. You wouldn't have thought so, but I am sure they wouldn't have been trying to set a record and just making it up.
Rooftop tents are definitely cool... but I don't see the benefits over just throwing a traditional tent into the back of a truck/suv. Time wise most decent tents can be put up in maybe a couple minutes. Sure, your tent is raised off the ground, but for multiple day campsites you are forced to completely break down camp it you want to drive anywhere.
On my f150s it was a difference of 12mpg (2016 w/5.0 above cab) to 17mpg (2020 w/3.5 ecoboost below cab) you do have to sacrifice a lot of bed space but on the bright side nobody has asked me to help them move
Did you account for elevation? Was the destination higher or lower in elevation from the start position and did you account for prevailing winds? You may have had a tailwind all the way home. Should have been 2 runs in the same direction really because anything could happen over such a distance.
Pro tip, clear your cruise control setting prior to filming the trip computer. Set at 85mph, which I know is only 5mph over the 80mph Utah speed limit (or is it 75mph outside of Hurricane, I forget where it switches to 80]. Enjoyed the video and the Lambo joke. Missed the opportunity to say: “We drove a vehicle with lambo hurricane visibility in Hurricane.”
And if you want to save even more, leave it in the garage when you aren't camping. That goes for ski and kayak racks too. Some people leave them on all year long as some sort of badge of honor or something, "Yeah, I ski" and wait gas leaving the rack on all the time.
My '07 Dodge with the 4.7 got about 17 hwy, too... HOWEVER, this new truck can do the same mpg with nearly double the HP and far more tech and a much better comfort level. Still pretty impressive, imo.
I'd like to see an MPG test were you do three different types. One type would be driving a pickup with the tailgate down. The second trip would be the same pick up with the tailgate up. And the third trip would be with one of those bed covers. Same trip same truck all type all three times with the cruise control on
MPG tests should always be A-B-A to even out elevation and wind et.c. But with that distance it might even out anyway or make the elevation difference neglectable.
Think you need to do it on your 100 mile loop. Cuz the way u did it, it could have been more uphill one way and downhill the other which would skew the numbers. Granted I expect an increase, but this probably isn't 100% accurate
4:25 - Utah resident here, I know it's silly, but Hurricane, UT is pronounced more like Hurri-cun, almost like there's no vowel between the 'C' and 'N'.
@@DJR5280 I've driven past the Hurricane exit on I-15 a hundred times but never been. There's not much there but the desert landscape is really nice. it's really close to St. George where you'll find a bigger town with retired folk, students, and some druggies. If you're interested in the area I know a TH-cam channel that's based there: Matt's Off Road Recovery.
Thats quit a bit of savings actually at those low numbers. I've been waiting for someone to do a vid like this. If I ever put a tent on my truck a rack system like this is probably a must. It'll pay for itself in the savings over time. Where I live right now thtas $177.53 cdn vs $146.78 cdn. I live in Canada and gas is around $1.1/litre right now. Thats a savings $30.75 cdn for a trip like that. Thats add up quick pver 4 or 5 years.
Why was it 648 miles one way and 621 miles back, seems like they took a different route? I would think that maybe they should do the 99 mile long f mileage loop TFL use to run.
Prevailing west to east winds and aerodynamics will be of consequence. A 1/4 mile elevation difference in home vs destination is of minute consequence over 650miles.
Did you take into account the elevation of both the starting and ending locations? Also, on your way out you were comparing the fuel economy from the vehicle's computer and your own calculation. You said the difference is about half a gallon and that's not correct. The difference is half a mile per gallon.
Rooftop tents don't make sense in the US. Nothing is going to kill you if you're sleeping on the ground. Get a nice big tent, nice pad, sleep on the ground.
At time 3:52 your tach shows 3K RPM on what seems to be level road. Why is it running so high? not good for MPG. Are you manually shifting and holding a lower gear?
Maybe I missed it somewhere in the video, but what speed where you doing on the interstate? I've driven a 5.3L Chevy Tahoe on the highway and easily logged 25mpg... at 70mph.
Oh gosh that’s a lot of fuel for not many Miles! I won’t complain about the small Turbo Diesels we get in Australia ever again 😜 35 Mpg for 150kw 500nw - not an awesome V8 but better touring!
Around 4:20 it looks like the cruise was set at 85. Not sure how Chevy sets up their gauges, but that’s what it looked like. It probably could have been 1-2 mpg better both ways by just slowing it down a bit
There are so many comments about the efficacy of this test and while I've often given TFL grief for some of their conclusions this is simply a fun sort of "what if" piece done for entertainment on a drive they were going to make anyway. Is it scientific? Not in the slightest. In order to know exactly how much the tent position effects fuel economy you'd have to run in both directions exactly the same mileage with the tent both up and down in nearly identical weather and traffic conditions. Or, more simply, just ride over to a stretch of eastern Colorado and run a fifty mile flat loop both ways with the tent up and down. Much more likely to get similar weather that way with way less traffic in the mix. In any case the video here is not misleading it just may not be showing precise numbers. Considering that there is more elevation gain returning from St. George than leaving from Boulder I'd say the real difference is probably larger than shown because the elevation gain would have otherwise reduced fuel economy on the return trip if no tent were present. Of course, I'm sure there will be another event in St. George and they could simply remove the tent altogether to see what difference it makes.
“We’ve basically turned this thing into a Lamborghini” 😂😂😂 Nice!
Loved that comment! :D
1300 miles of driving in a 10 minute video... impressive!

Young kids and their new math ! What they dont realize is it could be all uphill one way and all downhill the other !!!
true. but there will be a difference regardless. probably not 2.4 gallons though. maybe like 1.
Hey Wayne, in their case they would have had a much longer uphill run coming back than going. Lowering the tent makes a difference but exactly how much is impossible to say without identical tracks and test conditions. Still, 2.4 miles per gallon on a longer uphill run is significant.

That is probably getting too specific but the results already speak for themselves
There’s more overall elevation loss driving the first segment
Boulder CO is at an elevation of 5400 ft. Hurricane UT, 3200 ft.
There is. Plus the Rockies they have to climb over.
The destination in UT is lower than in CO, so in reality the difference is probably much larger if you were to go on a completely flat plane.
Morning Alex and Case!!... Love the Trailboss Truck!!! Great video guys!!
Maybe if You put the front of the roofnest a notch lower than the back, You'll get extra downforce, like having a spoiler, lol.
🧠
that would make the fuel economy worse.
Downforce= handling
Downforce=/= extra mpg
Hi Alex and Kase 🙂, excellent video content on this episode of TFLoffroad, very cool to see the difference in mpg by lowering and raising the camper.

Not a good comparison due to elevation changes and such. You have to mimic the speeds and route to get closer accuracy

85 MPH for the cruise control on the way to Utah, not the best for fuel economy.
There are so many comments about the efficacy of this test and while I've often given TFL grief for some of their conclusions this is simply a fun sort of "what if" piece done for entertainment on a drive they were going to make anyway. Is it scientific? Not in the slightest. In order to know exactly how much the tent position effects fuel economy you'd have to run in both directions exactly the same mileage with the tent both up and down in nearly identical weather and traffic conditions. Or, more simply, just ride over to a stretch of eastern Colorado and run a fifty mile flat loop both ways with the tent up and down. Much more likely to get similar weather that way with way less traffic in the mix. In any case the video here is not misleading it just may not be showing precise numbers. Considering that there is more elevation gain returning from St. George than leaving from Boulder I'd say the real difference is probably larger than shown because the elevation gain would have otherwise reduced fuel economy on the return trip if no tent were present. Of course, I'm sure there will be another event in St. George and they could simply remove the tent altogether to see what difference it makes.
Now remove the rooftop tent and compare the mpg.
