I think you're looking for a great rv. I know of a couple garage coaches for sale. This one is a bit outside your age, but I don't think age matters much on these rigs: 2006 United Specialties Garage Coach RV for Sale | RacingJunk Classifieds
That one actually belongs to somebody I know in MN. I haven't seen the inside but from what I know of them I bet it's in pretty good shape.
Here's another one: https://www.hawkengineering.com/4509gcddgta0csb.html
Both of these coaches are built arguably better than a Renegade. The United and Hawk are built on a steel tube cage with aluminum sheeting on the outside. Pretty sure Renegade uses a FRP panel construction. Do some research on both types and see what you prefer. I'm very happy with the quality of construction on my United Specialties. I've heard those Hawk coaches are made extremely well too.
I've got no connection to either Hawk or the owner of that United (other than she used to cut my dog's hair before she retired from that).
