Florida, weclome to our website and forum. We are glad to have you join us here. I have not seen this systme for a motorhome but it sounds like a lot of weight that a normal reciever may not be built for and most coaches are not designed to handle. A sport lift would be one thing for a motorcylce or golf cart but a car would be much different. Good luck to you and let us know what you find out.
