/diy/ - Do It Yourself

My questions are: is there a better "off the grid" toilet?
Is there a better place to move where land is cheap, and tiny houses don't have restrictions?
Any suggestions for anything?
It's going to run on 12v. Hopefully as many solar panels and battery's as I can get on/in. It's going to have a nice little rounded stand up shower from Lowe's, probably with just a high pressure shower head. Sink water and shower water (depending on where I end up parking) will just get emptied onto the ground. Aluminum siding will probably be about 2 grand. Going to use a propane fridge, propane stove, propane water heater (probably 5 gallon, more if it'll fit.) Dual axle tow behind trailer. Any questions? Concerns? Ideas?
