Wow, water really got to that! You questioned in the video if the zinc bolts reacted with the aluminum frame. They are pretty close on the periodic table so reaction with them touching would be pretty low. If Zinc comes in contact with metals further apart like copper, iron and steel then a reaction is more favorable and the aluminum will break down.
I never said it in the video but believe the reaction in question is; the water leached 'tannins' aka tannic acid out of the poplar which created a corrosive that corroded the aluminum.
@@WorkingOnExploring I can agree with that. That is certainly a possibility. Good luck on the repair. I hope this time you get it right. You never have time to get it right, but you always have time to fix it. Ain’t that about how it goes? Safe travels!
I have a question, do you think condensation from temperature between inside and outside could be a problem? On my last two campers when I had temperature change from inside to outside, I could see the aluminum studs in the wall from the outside sweating early in the morning. I often wondered what kind of problems are in front of me.
Aluminum definitely causes condensation, but the interior of the walls are dry and unventilated so there is nothing to condensed there. There can and will be condensation inside the cabin if there is enough, a) humidity in the air inside and b) enough thermal conductivity between outside cold temps and inside. Most of my wall strength comes from low thermal conductivity wood but in a very few areas where I have a concentrated load, like the 100lb spare tire, I have placed aluminum in the walls. There is 5mm of plywood on both sides of the aluminum and I have only a little condensation that is not a problem. I have a LOT of condensation that IS a problem with the aluminum window frames. If I had it all to do over, I would probably use the same construction again, because there are few good alternatives to do otherwise. My other option was to use an extruded fiberglass square tube instead but didn't for cost and mechanical reasons. I was a plant engineer for Safari Motor Coaches and we used aluminum tube framed walls and an exterior aluminum skin that had terrible condensation problems that there is no way around. I'm not a fan of a thermally conductive path through an RV wall so advise very selective use of aluminum.
Yea. I had one and used it (mostly) but the camera woman comes by randomly to video so I just grabbed the grinder and started (several times) to give her the shot...so I am guilty...

Dude! Respirator! When you're grinding in all of that dust I just cringed. Take care of yourself!
