I'd suggest you lose too much interior space with a slide-in camper and they have storage issues, as they don't have wheels allowing you to maneuver them around your yard / garage when not in use.
Either go with a pop-up (roomier and easier to deal with) or step up to a full-on RV (which is more money).
