One of my requirements I absolutely want to include is that any camper must fit into my garage. I also don't need to have fresh/gray/black water tanks since I really don't want the hassle of winterizing/sanitizing an RV.
Looking around I did find some small toy haulers. Like this one from InTech.

It is a low enough height and length overall to fit in the garage and barely fits my bike... if I remove the bike hitch and mirrors. And I would need to have ramps to load the bike. Inside is about the same head room as the Vistabule but the floor is just over 8 ft long. My bike is less than 8 ft by a few inches so it would barely fit. There is a pull out kitchen drawer with an electric fridge/freezer and cook top and some storage.
