Oh yeah, 68" is great for a camper but we just want a shell. Getting old is awesome. I'm about to pay almost $15k essentially for a place to stand up and pee in the middle of the night without crawling out of an RTT. I know, a bottle works but she doesn't approve and it's not the same. I only need a bed without condensation and a place to stand up, dress, make coffee and then I'm outdoors. I have had several homebuilt camper vans and one SMB and I'm loving the off the shelf capability and simplicity of the Tundra, I just need a bed.
On the shelves and interior space my plan is a to make one modular, maybe foldable shallow counter up the right side with a sink draining to ground at the rear. Then we can sit the Aquatainer on the counter beside the sink. Inside will also include a diesel furnace and a porta potty, otherwise all camping and living outdoors.
