OP, also thinking that if you have a 5th in mind you love, you truly can get a motorcycle carrier welded onto the back. It means you get the camper you want, just haul the cycle on the back.
we might be doing this with our golf cart in the future. but what I get welded onto the frame for hauling will be intense, but I can spend $5K on that but keep my camper as my #1 important floorplan I want most.
just an option to consider. when spending bigger bucks, take your time to get the set up you really, really want. I will be :)
