I know you mainly posted about Tacoma, but then posted about other vehicles. If this is something your going to be traveling in and living in, the # 1 vehicle that people use to live in/boondock in is the ford econoline vans. Mainly you buy the 18 passanger E350. you can get them for cheap and you just build up the inside for cheap. To include bed, cooking area, bathroom tables ect ect. Something you can full time live in. There cheap to get, get decent mpg, reliable, Parts are verywhere. Just me 2 cents.
Also you can get lift kits and 4x4 and diesel yada yada yada if you were worried about getting around. Theres a reason why these vehicles were used as fleet vehicles for every type of profession for god knows how many years.
