I will definitely take Almost There's advice and ask a shop about taking out the rails. Also, I had no idea that stuff would absorb moisture. It is definitely going! I'll keep the carpet because it can be repurposed.
I tried to see if someone would take out the rails for the seats, but no takers.
I will try to get the rails out of there, plywood down, and the wheel wells boxed in, and a non attached bed across the back. I really have to do some thinking about the bed because I really would like it to double for a couch, but I have to have 25" clearance under it for my non motorized recombent trike.
Then I will have to find someone to put 30 amp in it because in the Nevada desert I will have to have an air conditioner, so I might as well have an outlet or two. I had 30 amp in my cargo trailer and it was nice to plug in and I could get away with an hour or two of generator use if I couldn't plug in. We were able to get along just fine without electricity for short bits of time.
When I get all that done I'll work on the walls. Or at least I think that is how I should progress?
At some point, I'll add solar.
It will be parked and my daily driver for the next couple of years. I plan to retire in 3-4 years- hopefully 3 years. I have to pay for the van and I want to switch the trailer I have now for a Casita. I'll use it for the kitchen and bathroom and the van for my bedroom, office, and garage.
Getting ready for a retirement that I will enjoy is taking a lot of thought and planning. I told someone the other day that if my ability to wander was taken away part of my soul would die. She looked looked at me as though I had lost my mind. But, here, I think, I'm preaching to the choir...
My family doesn't even know my whole plan- they still think I should buy a cheap house and settle down...
Thanks again for all the help and suggestions l!
