My 5th wheel RV dry weight is 7530 lbs and loaded is 9950 lbs. Truck is 2014 F250 6.2L 4X4 Crew cab (max load 12,200 lbs). Would there be any benefit installing air bags on the truck ?
I don't think you should need airbags. My 13 250 will easily carry 2000#s pin wt. If you are loading your truck heavy, with added gear, people, etc, then maybe.
What is your tire loading sticker showing for payload? Mine is 3,232.
