@ZMAN :
Pretty cool project. I've mentioned to my dh about building out a nice size trailer for the same purposes. I don't need all the fluff of a camper to camp. I need shelter and cooking. I also talked about building out a box truck for a mobile office. Let me know how it goes. I've taken myself down those camper vs rv rabbit holes quite a bit. Almost was talked into a $300,000 tour bus class A, or the 5th wheel with the back and side porches. Lol I'd need a $100,000 truck to pull that with. Then the hole maintenance thing of an rv and the like, the replacement part costs, the emergency fund needed for hotels etc in case of break down. Many many rabbit holes in 3 years of reach, videos, salesman. I like your project idea. Simple comfort and the ability to eat. Nothing more needed and very low maintenance.
