billyray50 - we were talking about rating a dually, hence the x2. But to test the rear tire theory is your SRW payload 4510#?
Anyone heard of this trick? The Ford salesman told me that they were taught to take the GVWR and subtract the GAWR (rear axle) to obtain a payload rating. Has anyone tried this trick - do you think it's accurate? My impression so far is no, but hard to tell with so many different numbers to look at.
I'm still shocked at the 1 ton DRW with the cargo weight rating of 2450# - even if you add 900# for 6 passengers at 150# each you come up with 3350# which isn't enough for the 10'1" Lance fully loaded. Cars.com estimated payload for this vehicle at 4164# and it's hard to imagine that it wouldn't handle a non-slide Lance camper.
