Our goal: travel trailer turned tiny home!

Hopefully you have finally gotten discouraged enough give up on your idea. Its just not practicle in the real world. No gas, means no heat. There are just not enough batteries in the world to keep a TT heated with electricity strictly using solar in the winter in PA. Without adding massive amounts of insulation two inch walls of RVs dont provide enough insulation value to be worth squat. Once you did have this monster built where would you park it? How would you move it? Most established RV parks would refuse entry. Most local governments would prohibit you parking it on private land without water,sewer, and power for long term.
This is just to practical or a smart idea. Too many pit falls.
