When I ordered my new Landmark Mesa, I was not sure I could back it up my sloping driveway without dragging the hitch, so I did not order one. Bad idea! Now I know I can get up the drive with one, but am unsure about where to get one. Has anybody purchased a hitch with a 2" receiver to install on their unit. Mine has flanges on either side on the rear of the frame to secure one. Does HL sell these to match (measurement wise) the Lippert frame they use, or are the measurements pretty much universal? Where else can I get one? I plan on putting a 2-bike rack on it, so not much weight. Any help would be appreciated.
