Here are some of mine. Its not done but I have used it this last fall for deer season and stayed in it for 2 weeks with no problems. I have a 12k btu furnace that I took out of a rv and just about everything else thats "rv" came out of one. I have less than $500 in parts into it right now.
Things I have planed for this spring are a 32x32 shower in the front left hand side of the box. and a set of fold up bunk beds across from the counter. I want fold up ones because I still haul stuff in the back when needed. I also have plans to but a folding deck off the back, I want it the same size as the back of the box. I'll put a 12v winch mounted on the roof to lift it up into place when Im moving. Its kinda cold here right now so just about everything is on hold till it warms up. I had more pics of it when I was using it, I had a futon in it to sleep on, but I cant find them on this computer right now.
