PS: Where do you find the "max pin weight" rating? I've only ever found the GVWR and axle ratings. Or are you speaking of the rating on the hitch which is independent of the truck ratings?
Its common for rv folks to claim their trucks gvwr based payload sticker is how much pin weight or truck camper weight they can load on their trucks rear axle (in the bed).
There is no one ton srw that can carry those big gvwr based 4000-4500 lb sticker loads in the bed over the 7000-7250 lb rawr without exceeding tire/wheel an rear spring pack.
They would need higher rated tires/wheels and rear suspension.
Another fallacy of using those new high gvwr or the payload sticker to figure how much pin weight...or truck camper weight their trucks can safely carry.
