My produts are avaible to see on my web-site ***** For the last 9 years I have carrier from this web-site and by referrals of satisfied customers. These are self installed carrier which enables a woman to change a flat tire. By incorparating a bicycle crasrrier into the spare tire carrier it complets a package for all travelers. Constructed of heavy steel and powered coated finish and rust resistant hardware. These are inserted into a 2" tow hitch which makes it possible to be moved to a new unit if desired. Therefore it becomes a investment rather than a special item tailored to a perticular unit. In the 9 years of selling I have never had one returned or seen one for sale ***** has enhanted all the units that have had one of my carriers installed. With installion of the norrisway carrier on the back of a unit it increasses the safty factor as it creates a large bumper that is suported from the frame. Lot of the RVs now have only a fiberglass shell therefore in accident in the rear there is no protection from a high truck or any verchile that plows over the bumper on most autos or RVs.
