Thank you everyone for the warm welcome, compliments, and encouragement. It's been a fun project.
We camped out of the Tundra with a basic canopy topper for years. I had a small kitchen setup so we could get out of the weather to cook and we had plenty of room for gear and dogs. We slept in a small tent. Life was simple and good, then time caught up with us and we both got tired of crawling in a tent, getting dressed laying down, and cooking all hunched over.
I started researching pop up campers, they seemed perfect for our style of travel, and quickly decided on either a FWC or an ATC. I looked at new ones, but couldn't imagine paying as much for the camper as I paid for the truck. I looked at lightly used ones, but even those were more than I wanted to spend on something I would just use and abuse. I eventually ended up on the Wander the West forums and realized that it was possible to rebuild an old one. Reading through all the rebuilds gave me the confidence to do my own.
For now the goal is to have a lightweight, basic, functional camper that I can use for a few years with a minimal investment of cash, then worry about making it look good when I'm ready to sell it. No point making it look nice right now, the two humans and two dogs would only make a mess of it. I've realized it will be an ongoing project and that is part of the fun in it.
Only 30 days and one more holiday to get through before we hit the road for a while...
