If it is just yourself I would keep the camper. We set up 3 wall tents, have a 16' cargo trailer that we build a kitchen off one side. It takes a long time to set every thing up. A few years back another friend of mine joined our camp he has an 11' camper with a jeep he tows behind. He doesn't even unhook his trailer, just jack knives it so he can get in and out. When we started to break down camp he walked out with his remote pushed the button his jacks went up slide went in. Jumped in his jeep drove it onto his trailer (no ramps needed) tied it down and was ready to go in less than ten minutes. It takes us days to get every thing set up and about 4-5 hours to break down. Then the work still isn't done because you have to unpack everything when you get home and dry it out cots, tents, tarps, etc. I love the comfort of my wall tent but if there wasn't several of us I think I would have a camper
One nice thing about the RV is that when you have guests, they can use it as a guest house.
