""So, using cancellations, maximum 5th wheel weight: GCWR=18,000- truck 7,190 lbs = 10,810 lbs. 5th wheel?????
20% of 10,810 is 2,162 lbs. looks like I am over my pin weight? """
YES you will be over...
Not just pin weight (payload) but also trucks GVWR (8800#) 7190 + 2162 = 9352
BUT..you will most likely be under RAWR/Rear Tire Load Rating
Stay under GCWR, RAWR, Rear Tire Load Ratings (going over GVWR isn't all that bad)
SO a 10K GVWR 5th wheel would be doable
ANY upgrades/mods will make for better towing but will NOT change the mfg. numbers/ratings
