So far, I've only found one manufacturer of an aftermarket Class IV hitch with a 36" extension (I need the clearance, as I'll have a 11 ft. slide in camper on my F250 HD) that being Torklifts Superhitch. Are there other manufacturers of the same type hitch or possibly other options?<br /><br />Also, can anyone recommend some quality, frame-mounted camper tie downs?<br /><br />Torklift here in Kent, WA, wants approx. $1000 for both the camper tie downs (frame mounted, spring loaded, and turn-buckles and hardware) as well as a Super hitch with the 36" extension. Seems high to me, but what do I know? I'm transgressing from towing a trailer, to towing a boat with a camper....<br /><br />Advanced thanks!
