Of course, if you can get by with less, you could buy a camper shell and camp in it, too.
The reality is the only thing a nonslide TC has in common with a modern multislide TC is they both are carried in a pickup. As previously noted, my TC was built in 2005. 15 years old with nothing wrong with it. Also as previously noted, there are Northern Lites and Bigfoots that had significant issues that were way younger than that. I think most people with issues are hard on stuff or don’t maintain their TCs, or both.
If I would have been worried about resale, I wouldn’t have bought an RV.
