Just because you can adjust the stiffness of a vehicle doesnít necessarily mean it will have a higher towing capacity. A good example of this is a Ford F-150 HDPP vs the Max Tow pkg. The HDPP has a...

Nice analysis! Just curious if you have weighed the actual tongue weight without the P3 attached to the trailer? Consider the weight of the P3, the actual trailer TW maybe closer to 10% -10.5%. For...

Of course it does. We were discussing the differences in weight removed from the TV front axle based on the trailer tongue connection point and the static stability issue it creates.
