If your receiver on a class A is tucked under the chassis this will not work without an extension.

Cannot use right out of the box on the back of Winnebago motorhome. The receiver is tucked under the rear of the coach and in order to use this carrier the pedals and handlebars need to be removed. I gave 3 stars because while the rack is well designed and well made, nowhere does it say it won't extend far enough. I read a lot of reviews here before I bought it, and came back and read more trying to figure out what my next move would be. One reviewer mentioned an extension, and I found one here at Amazon designed just for this purpose -- to use a bike rack. It's annoying a product made for an RV doesn't not state it is designed to work on only a trailer or class C camper. Another issue is we will not be able to use either our furnace or generator while it's inserted in the receiver. In my photo you can see the receiver under the body of the coach. The two vents in the center are for the gas furnace and the tiny pipe in the lower left of the picture is the generator exhaust pipe. While the furnace is not an issue, in California's 100°+ Central Valley, we frequently run our generator while traveling to power our air conditioning. I'm not certain it's possible with bikes a mere inches from the exhaust.
