Thanks Hanno,
I should have checked that one too.
Adding the F15A Chassis/cab weight plus body weight plus double the load rating (2 x 15 cwt) gives 10,047 pounds, which is close to the allowable maximum for a C15A.
What difference would be in a cab 13?
I know that post war in NZ, when the army registered their fleet for the road, many C8AX were rated at 15cwt load, and some at 1 ton.
This fits with the system where off road ratings were half of the on road ratings e.g. 5 ton for a 6x4 GMC, and 2.5 ton for a 6x6. BTW are these US vehicles rated in the short ton (ie 2000 pound) or the long ton (2240 pound)?
Using the long ton, 3.5 ton is 7840 pound, so that leaves 1153 pound for payload, about half a ton. F15 would be more.
