Like Bill & Laura, we're pulling our '89 Bigfoot
5er with the rail mount Anderson Ultimate 5th Wheel Hitch. We use the rails that the truck's previous owner had installed. Have to say -- it's a DREAM! We used to kind of dread hooking up but now, it's so easy plus it pulls really smoothly and doesn't clank around or make much noise at all. And did I mention that it's easy to move around, in, and out of the truck bed? We were completely new to 5th wheels when we got our Bigfoot
and came across the Anderson by mistake. We're so glad we did!
