We have a 26ft. bumper pull. I bought it from parents cheap about 10 years ago. We only use it 3-4 times a year.

If you don't plan on using one a whole lot... definitely find a nice used camper. They can be found really cheap for ones over 5 years old.

I prefer a bumper pull so that it doesn't have to have the big 5th wheel setup in the bed of the truck.

Slide outs can and will fail...although they have gotten better over the years. Keep the screw mechanism lubricated.

If you have a good truck then a camper is a cheap way to go, but if you don't then a motorhome might be a better way to go. Both are built basically the same way so the difference would be pricing and ease of use.
