Air in general is a good thermal insulator. It makes sense with all that open space in the closed truck bed, that the “under bed storage” stayed the coolest.
Glad it was helpful! There are several factors and variations I didnt cover, like what happens when you are driving for 4 hours down a hot highway, versus sitting in its own shade in my driveway? You would expect a lot more heat from down below, right? Anyway, food for thought.
@@marksevlife totally agree. Knowing frunk gets hot with the motors nearby, would that be hot mid travel, and would the pickup bed cool down at all with air movement mid travel. Newer gen truck feature request - temperature sensors throughout!
I enjoyed this experiment. I'd be interested to know what the cabin does in my desert climate, when July & August temps are at or above 100°F. This was always my hesitation getting a glass roof vehicle.
The glass roof is definitely an issue with heat. I was going to talk about this for a bit in the video but just wanted to get it out.... On long trips with my Tesla, I wont do it without my roof visor in place, it makes a huge difference, you can feel the sun heating up your head. I have yet to find a Rivian roof visor that is made for the truck, so I dont use one. And either the Rivian has stronger tint on the roof, or Im just so happy to drive it I dont care about the sun.
@@marksevlife Thank you. I'd be interested in a temp measurement of the inside and outside of the roof glass while in direct overhead sun. And a sun shade recommendation when you find one. Excited to get my R1T.
Hey Mark, interesting set of temperature observations about where or where not to store things in your Rivian on a hot 🔥 SF Bay area day. Since I'm a weather buff as well, could you share more info with us about the device you have in your roof which collects data? I'm going to listen to that part if the video again. Thanks!
Right on. It is called Tempest and it is made by Weatherflow. I like it a lot. I am actually a subcontracted contributor to Weatherflow; I post wind forecasts for the SF Bay Area a few days a month on their site iKitesurf. But I hope this video does not come across as a promotion or product placement. I actually had to buy the device, it was not given to me, so in that sense this doesn't meet TH-cam's terms for "compensation" to mention a product. So yeah, go check it out if you're looking for one.
I did actually, about a week later. On a day when it got into the upper-90s. And it was cooler down there in the "under frunk", within a few degrees of the under-bed sensor, to it was the 2nd coolest spot! Thanks for the comments
I have driven for hours in the hot sun in 90 degree temps, then grabbed stuff out of the frunk upon arrival, and did not feel any discernible heat up there. But I could try and make that a test.
I think a white truck would make a difference yes, cooler for sure. The blue and many of the other non-block colors would be about the same. Just guessing though. Thanks for commenting!
I have not noticed any heat up there honestly. I just fast-charged Sunday on the way home from this day of shooting, fast charged at over 200 kW speed, and I did check in on some items in the frunk and they did not feel warm. I did not use a sensor though.

Thanks Frankie for the thoughts.
Appreciate this - was hoping to do a similar experiment and you nailed it!

@@marksevlife thanks for the information about Tempest. Your comment about the device seemed to me like an afterthought, definitely not a promotion!
Would be interested if you would do one under the first level of the frunk below the panel. I would assume it would be a lot less with that barrier.

Now do it driving in the summer. I bet that frunk gets super hot with the radiator up there
No radiator. There is a A/C condensor
@@jasons7044 there has got to be a small radiator for battery cooling right?
@@carperdiem8754 they are separated from the frunk, but they are small closer to the size of a transmission cooler, then a full size l radiator.
I have driven for hours in the hot sun in 90 degree temps, then grabbed stuff out of the frunk upon arrival, and did not feel any discernible heat up there. But I could try and make that a test.
@@marksevlife that feedback is all I needed. So it sounds like ice chest mode for the frunk might actually work, awesome
How much do you think truck color affected these results. Would you think having a white truck or blue truck would have made any notable differences?
I think a white truck would make a difference yes, cooler for sure. The blue and many of the other non-block colors would be about the same. Just guessing though. Thanks for commenting!
How are people supposed to camp on the bed if it's that hot?
If you have one of those tents over the bed, they should block the sun from hitting the truck tonneau cover and heating it up.
Front trunk would be a lot hotter if this was done while fast charging on a road trip
I have not noticed any heat up there honestly. I just fast-charged Sunday on the way home from this day of shooting, fast charged at over 200 kW speed, and I did check in on some items in the frunk and they did not feel warm. I did not use a sensor though.
@@marksevlife that’s surprising. I’ve seen mine get pretty toasty.
