I've got an F150 with #1920 payload and a un-realistic "tow rating" of #11,300.... Ha, ha...
I'm towing a #7000 GVWR TT that's only 26' long and it's all I want to tow with it...
Don't get me wrong, it tows my Rockwood GREAT.. I just don't want to tow much more getting to the max limits of the truck.. (I pack HEAVY, so I know I'm at the TT's GVWR easy...)
I'm using a basic EAZ-Lift #1000 WD bar and chain hitch setup. No friction 'sway bar'.. Just have it setup right and been using this same hitch for over 17 years..
Anyway, good luck with it. Mitch
