There are many of us out there that are not 100%. I have needed a walker for 10u years and carry a Travel Scoot electric scooter in my roadtrek when travelling. It folds to fit under my bed from the rear door and only weighs 30#. Since I also can't get low enough to operate valves for dumping I had a macerator pump installed so I can just sit on my walker seat and work the valves and switch from the seat. Got many miles on last summer with trips to Northern Ontario twice, Boston, MA. Chetek, WI. and a few small trips. I am not handicapped that bad yet but a Roadtrek does let me use handicapped spots when avavilable.
