TT Weight limits: theory and reality
There are a ton of threads here regarding the proper matching of TV and TT. Based on what I learned here, I made a very expensive decision to upgrade my brand new 1/2 ton to a 1 ton TV so that I would...

Ford uses the same brakes on all F-250s and F-350SRWs. GVWRs for these trucks range from 9900 to 11500#. Adding nearly 2000# to the GVWR does not gain anything in braking capacity.
I did not say the brakes used on the F-150s are the same as the brakes used on the F-250/350SRWs.I do hope you realize that the coefficient of friction only comes into play when the tires are skidding.---I do not realize that -- and it is not correct.
The maximum braking force occurs near the point where the tire is just beginning to slip.
Maximum braking force occurs at the optimum slip ratio which usually is in the range of 10-30%.
"Freely rolling" means a slip ratio of zero, and "skidding" usually implies a slip ratio of 100% (wheel has stopped turning).

I am glad you realize that maximum braking occurs slightly before lockup. Thanks for the reply. By the way, even if it is only a four percent improvement in braking, I'll take it. Sometimes only a few feet make a difference.
