Question on F150 Eco GVWR

Hello all,

We are zeroing in on our new TV - we've decided on an F150 SCREW... previously looking at a Suburban but the GVWR was too low on the 1500 and the 2500 was out of our range.

I've researched the differences in the max tow package and standard tow package, and there seems to be some strange inconsistencies in the GVWR that don't make sense. A 145" WB with the std tow and 3.55 rear has a GVWR of 7200#, GCWR of 15500#. Same vehicle with the max tow package has a GVWR of 7650#, GCWR of 17100#. Only difference is a slightly updated hitch (extra 800# capacity)and tow mirrors. The 3.73 rear is a requirement for the max tow, but you can find 3.73 rears without the max tow, and their GVWR is 7200#. I've inspected both on the lot and the suspension is identical, same number of leaf springs, same shock part numbers, etc.

From my understanding, GVWR has everything to do with frame, suspension, brakes, axle, etc. Here's how the axle ratings flush out:

MAX TOW
GCWR: 17100#
GVWR: 7650#
Rear GAWR: 4050#
Front GAWR: 3750#
Axle Ratio: 3.73

STD TOW
GCWR: 15500#
GVWR: 7200#
Rear GAWR: 3850#
Front GAWR: 3750#

The max tow pkg has a combined axle rating of 7800#, and std tow has a combined rating of 7600# (adding the two together). So therefore, if the combined limit of the axles on a std tow F150 is 7600#, why is the GVWR only 7200#? And if the max two gets you 450# additional capacity, why is there only a 200# difference in the two?

Here's why I care: I'm stressing over whether to get the max tow or not. They aren't easy to find in the XLT with the specific options we want and we don't want to order it. Plus, we aren't big fans of the mirrors, preferring to use slip-ons when towing. This vehicle will be used mostly as a daily driver for my wife, and we'll tow 3-4 weeks out of a year max. Our TT loaded for camping is only 5040#. However, when we do go camping, there's 5 of us which will put us at or slightly over the GVWR on a std tow F150. I think the numbers are a little fudged for marketing... suspension is the same, frame is the same, brakes are the same. The GCWR of the std tow F150 is 15500, which we won't even come close to.

Thoughts? Advice? Am I overthinking this?

Thanks, gents! Appreciate the feedback.
