The camper is custom built by me, it started out with metal frame, has 3/4 plywood on the out side 2inches of insolation and a paneling on the inside, yes the walls are 3'' thick and the camper stays very warm or cool with little help. It has 200watt solar with a control panel a deep cycle battery, I added a little propane camp stove to do light cooking in bad weather. It has running fresh water to the sink with a 16 gallon tank and a domestic electric fridge, or freezer depending on what you have the temp set to, that runs off the battery or will work on 110 power. I have camped 5 days and the battery has never been low with the solar. The bed is an actual Murphy bed that folds down. the camper is 8' wide 7' deep and 7' tall, this camper will work great on a flatbed truck or a trailer, a 20 foot trailer would make a great toy hauler set up.
I can send more pics of needed,
dont wast my time trying to scam it won't work and ill take your number and do a lot of things with it
