Heres what i need for an rv I'm hoping some of you here can tell me where to start.
Have at least 6'7" interior height space since I am about 6'3".
Small enough for me to maneuver along on back country roads so about 27 feet.
I will be using it to boondock for weeks at a time.
It just has to fit me and someone else occasionally in it, I plan to full time with it but i will be spending alot of time outside of it working in all kinds of conditions and going inside to pretty much sleep and shower.
It's going to be an rv for gold prospecting and rockhounding.
and the final thing is that it needs to be cheap.

I can weld, do the plumb, carpentry, electric work and install AC's by myself and i am hoping I can learn the rest This thing can take a year or two to build.
Well this is the end of my tall order i hope you guys can help
