First post of my Tiny Camper / Squaredrop.
I already had a 1973 Coleman popup trailer that I bought from a relative for $200. It was actually in pretty good shape for its age. But, one of the lift posts had a broken cable and one of the bunkends had previously broken and been repaired but still never worked quite right. It had a 15amp shore hookup but no converter for using a battery, no interior lighting, a stove and sink but no fresh or grey water tank, no toilet, and an odd smell that I'm sure is a mixture of years of camping, campfire smoke, BO, and vintage 1970's.
I forgot to take pictures of the tear-down, but after 2 1/2 days of blood, sweat, cussing, and realizing I was using a wood blade instead of a metal blade on my saw, I finally got the trailer down to bare frame.
