Like all DIY builds, strength depends on the method of construction not necessarily the materials used. How the joints are attached to each other is the largest issue.
Not to criticize your work, but I don't see how this video demonstrated strength. It seems like anything could make it down that trail one time. Maybe put some weight on the top like spare wheels and drive it down that trail.
This is a good site for small trailer builds http://www.tnttt.com/
 
Nice! Mine are still holding together as well. Nice thing about it if I damage it anyone can easily fix their own and if I completely total it I have very little into it. Worst thing about mine as it looks like a refrigerator and people keep wanting to know if I have ice! LOL!!!
 
Good to hear. Yes simple and economical and they keep you cool and or hot.
 
Does the trailer have condensation inside when sleeping in it in cold weather?
 
The thing I am finding is that there really isn't anything to come loose in mine. The basic structure is amazing. The problems are small but all are results of the holes and what gets put in them, things like vents, windows and doors. I used wooden dowels to fill the holes where I had used metal screws to hold things while glueing and therefore no screws to draw moisture or back out. My wife wanted a larger space and appliances for our base camp so she bought a new 25' camper trailer that after a year of just sitting I have already had to deal with issues caused by expansion and contraction in the siding. I hate to think what it would have been like towing down the road moving every two weeks or so to different boondocking sites! I see there is a company in Scottsdale AZ that builds houses with 8",12" and 16" foam with a resin stucco. They simply cut channels for wiring and plumbing in the foam with a hot wire tool. Now if someone could make that work on a trailer how great would that be. Sort of like a fiberglass trailer with no seams super insulated.
 
Mine did when using a buddy heater (way too much heat) but a smaller heater, few vents and air flow under the sleeping pad solved that. The nice part about it is in the summer being very white it stays really cool most of the day.

Yes, on metal parts there is condensation. No condensation forms on the canvas/foam that I can tell though. I did not install a roof vent which I would suspect would collect condensation too. By having the small vents in the corners this keeps condensation from dripping on the beding. I had two people sleeping in this one and it dropped down to 14* and we were fine condensation wise. I did crack a window about a inch around 1:00 because I kept waking up a bit short on breath. There are 4 2" vents in the trailer, but I don't think it was enough for that temperature with two people inside. After cracking the window it got colder, but I was sleeping better. Foamies are extremely air tight hence why I installed non closing vents. By being air tight they are also water and dust tight too. No issues at all with dust in my foamie and it follows my jeep all day long on dusty tails.

I have had the same results. We camped in late August were there was no shade in the canyon till around 3:00 in the afternoon (video posted above in fact). After lunch the kids and I wanted to take a nap. They slept in their tent, I slept in the foamie. I opened the windows and with the slight wind blowing through the trailer it kept it quite nice. Kids where out of their tent within 10 minutes. Way too hot for them...I got a nice nap.
 
That is how I installed wiring in my first build. Before I applied canvas I hotwired channels and box locations. Reglued the channels back in, faired them and applied canvas over the top.
