Hi Phoneguy; I still suggest that you talk to Guy at Arvika.com Guy is very knowledgeable and eager to help. When I was first looking for a bike solution, Guy answered all of my questions and guided me in the right direction. Arvika has a wide array of products to fit most any situation. These products are very well built and do what they are supposed to do; also transferable between vehicles should the need exist.
Good luck and happy rv biking.
