Class A Configuration

Well, I have another dilemna. I am a disabled person and have an electric wheelchair. I am retiring and dreaming of becoming a full timer. I would like to take a 4 passenger golf cart with me across the country to use at campgrounds and boondocking. I cannot imagine being without the electric wheelchair but would do just fine in a golf cart. I have looked at MH toy haulers. I need a real bed to sleep in (as does my wife) and the only Class A I saw that has that is the Newmar 3920/1. A 5th wheel is out because it is too hard for me to move about from truck to trailer. The Newmar 3911 with wheelchair lift is nice, but, I want to be able to ride around with my wife. I do not want to use the wheelchair while she walks as she too has walking issues. We will most likely be using a Jeep Contour as our toad. In the 10 ft. garage of the 3920, it will be a very tight fit. Garage is 10 ft. long, cart is 9'7". Leaves 2-1/2" front and back. Cart is 4.5' wide and wheelchair which would be parked right next to it is 30" wide. That leaves about 11" to share between either garage side plus the space between the cart and wheelchair. I also plan on having a washer/dryer stack or combo, not sure which yet.

My question is this: Is there another way to transport the wheelchair, golf cart and the toad? I have not camped in 28 years so have not seen the various possible configurations. This whole idea of a garage is new to me. I am trying to stay in a MH under 40 feet and I know somethings has got to give. Any thoughts are gratefully appreciated. Thank you!
