My MH is on the low Alko low chassis. Already a slight issue with ferries etc. I want to put two bikes on a tow bar mounted rack but need one thats sits as high as possible. Ive already ordered a goose neck tow bar that will raise it two inches and even enquired about air but a little pricey as its not really needed as the ride is already very good. Does anybody know of a rack that sits higher that the tow bar when attached. A rear mounted rack isn't an option on this MH
