We have a 26'
Born Free Class C that was custom designed for my wife's use from an electric scooter. Unfortunately, our health has also deteriorated to the point that we'll have to sell our coach soon.
It's possible to design Class C floorplans that can be managed from a Quickie sports-type wheelchair or scooter, but we found it difficult to retrofit a platform lift & chair-wide corridor into most existing Class C's. You can put a
Burr Handy-Lift on the outside of the box, but she'll probably need to be able to stand and pivot to a chair.
Karen is right; unless you rebuild the front seat(s) to level them with the rear compartment floor, it's tough to set them up for a slide transfer. (We used a
B&D Independence transfer base to allow the passenger seat to move between the front compartment and dinette area.)
If you have any more questions, send us a PM and we'll give you our contact details. (My wife was a rehabilitation counselor / supervisor for over 20 years, and knows a lot about adaptive equipment.)
