XL HDPP have less Payload than XLT/Lariat HDPP?
I was looking at the max payloads for 4x4 3.5L EB SCREW. Looks like the Lariat and the XLT have 230lbs more payload capacity, due to the 18" wheels. I always assumed a basic WT would have more payload due to less upgrades, though according to Ford's charts, it looks like the XL has less payload, due to the 17" wheels.

On another subject, the 5.0L NA has 30LBS more payload, than a 3.5L EB. Though you loose a lot more towing, due to the loss of the torque from the 3.5L EB.

Weight capacity of the tires - not the wheels - is probably the limiter. The stock 17" tires on XL trim have less weight capacity than the stock 18" tires with Lariat trim. Check the tire specs on www.tirerack.com

So at the risk of flogging a dead horse what in fact is the limiting factor for payload???

Payload = GVWR minus the weight of the truck. So if you restate the question to "what is the limiting factor for GVWR?" the answer is whatever component has the least weight capacity. Frame, springs, shocks, tires, wheels, axles, bearings, braking capacity? Probably only the chassis engineer that determined the GVWR knows for sure.
But it's probably not wheels or tires. For example, the tires on my F-150 4x2 have load index of 110 = 2337 pounds. 2337 x 2 = 4,674 on each axle, but my fGARW is only 3,600 and my rGAWR is only 3,850. So GAWR is a lot less than the tire weight capacity. And my GVWR is 7100, or a lot less than my combined GAWR. So obviously tires are not the limiter on my F-150.
Any truck manufactrurer would have to be pretty stupid to use wheels with less weight capacity than the tires. So I'm confident that neither tires nor wheels are the limiter as to the GVWR on my F-150.

Is GVWR a legal limit? I am guessing payload is more of a guideline, so long as you never exceed GVWR?
