Using Your RV more like a tent

We've had a old sunrader that was used for similar purpose. The waterpump was shot and so was the fresh water plumbing and the connections to it. Never really wanted to invest my time and resources to overhauling the system. Comming up from backcountry/ winter camping, having lights, fridge and stove that worked along with a toilet and a fiberglass wall to keep us away from the elements was a godsend. We purchased it for next to nothing, drove it everywhere, stayed anywhere and sold it for more than what we paid for it after we were done. Do what you like with it and enjoy it.
I didn't know how much I appreciated the comforts of the RV until i got one.
