Why yes I am insane and have papers to prove it

I have a 6x12 trailer I am converting to an RV. The insane part you ask... It's a 1985 Hallmark steel trailer lol
I already removed the rear and am welding 1 1/2 square steel frame to have a 3 ft by 57 inch wide drop door to slide a full mattress out. Going to custom fabricate kitchen cabinets (16 inch deep) in the front and all counter top and floor will be "Matching" pho marble using stone coat counter top epoxy.
Already have the FRP that I will be reskining the trailer with. (36 year old aluminum siding looks like hell) the frp is 4x8 sheets and I will be using Bondo on the seams
I plan to do the electric as a hybrid 12v system that will run off of solar with a battery charger system that will run off of a small gas generator if the sun goes fail me
Budget goal is $5000 max.
