I had an old square body suburban 2500 4x4 for about 25 years. It was terrible on gas, but it had a 40 gallon tank, I could sleep in it, stand on it, I could get most places, it survived a flash flood in the mojave, drove it through Mexico, Belize and Guatemala, and it was perfect for hauling a camp to that thing in the desert around labor day. 300k miles and finally blew a head gasket and the heater core cracked. Body and interior were in great shape, sold it to a friend who has fixed it and it's still going strong. It was an overlander long before that term came into vogue. Now, I have a toyota.
I'd get an EV, but, I'd get to the edge of the desert and then have to leave it because there's no charging in the middle of nowhere. Waiting for hydrogen fuel cell in my next life.
