I took a 7 week coast to coast road trip after being laid off from Boeing. I didn’t have a camper but realized that being able to pull off the road at a rest or truck stop was the way to go to make the trip affordable. With a few sheets of 1/2” plywood and misc. hardware this is what I came up with. The effort was well worth the time and materials.
when you wake up in the middle of the night thirsty as shit then go get some water and it tastes like jesus himself came down from heaven to cry wonderful distilled tears of joy into your cup
