How to carry a wheel chair or walker with a hitch mount carrier on my car?

What is the best brand of carrier that will mount to my 1 1/4 trailer hitch on my car to carry a walker, or wheel chair on the outside of my car? Do I need to use a bicycle rack?|||It depends on what style lift will fit your needs. Or if you want just a ramp style cargo holder. There are many types of wheelchair lifts and platforms, its a matter of narrowing down what you want, and how much you have to spend. I would certianly get something made to hold a wheelchair to minimized accidentally losing the wheelchair off the back. If you type " wheelchair car carriers ?" in the internet search box you can start clicking and research what is out there one click at a time, I have a Ricon lift in my van which is a good company, and Braun is another good company that makes lifts. I know these two companies have been around for many many years. how ever are fairly spendy, there are a lot of links to companies that make all types of products, It may be a good idea to find a mobility specialist of some kind in your area. so that you are able to go see what is available and get some idea of ehat it is going to look like and how it will fit. And you may need a cover of some kind for rainy days, a vehicle kicks gallons of water out behind it going down the road, and in short order what ever is on the back will be a dirty filthy mess if unprotected from the elements.
