Can I ask where you did your weighing? I weighed my TV at a Pilot but was worried the whole time that I was in the way. What do they charge for multiple weights? I think I paid $11 for the TV weight. Now that I have a different trailer, I need to do some more weighing.

It looks like you have done a good job of adjusting the WDH. The rear axle is 10 lbs. under the weight limit. The vehicle weighs 7580 lbs. attached to the trailer. That also may be close to the GVWR. Was the family in it when it was weighed?

Hit the scales again on the way to our site yesterday to re-weight with adjustments and here's where I'm at:
Expedition By Itself
Steering Axle - 3380 lb
Drive Axle - 3600 lb
GVW - 6980 lb.
Expedition and Trailer (No WDH)
Steering Axle - 3020lb
Drive Axle - 4700 lb
GVW - 7720 lb.
Trailer Axle - 5960 lb
GCW - 13680 lb.
Tongue wt. 7720 - 6980 = 740 lb.
Trailer wt. 13680 - 6980 = 6700 lb.
% tongue wt. 740/6700 = 11.0%
Expedition w/WDH (8 Chian Links from the bar)
Steering Axle - 3280 lb
Drive Axle - 4320 lb
GVW - 7600 lb.
Trailer Axle - 6080 lb
GCW - 13680 lb.
I decided since I was there I would give it one more go at 7 links
Expedition w/WDH (7 Chain Links from the bar)
Steering Axle - 3340 lb
GAWR 3700 lb.
Drive Axle - 4240 lb
GAWR 4250 lb. !
GVW - 7580 lb.
Trailer Axle - 6100 lb
GCW - 13680 lb.
So at 7 links from the bar the steering axle is only 40 lbs different than the Expedition with no trailer hooked to it. Drove to our site 110 miles from the scales and I couldn't believe what a huge difference it was from last weekend. Much more comfortable drive to the point my wife as a passenger could tell it was better. It was more solid, didn't feel as bumpy when we hit any uneven spots in the road and when we got hit by wind instead of feeling squirmy and getting pushed I could feel the Expedition hold steady and the trailer almost 'snap back' in line. Thanks the info on needing to go back and get re-weighed with the different setups.

(c) Its load rating shall be that specified in a submission made by an individual manufacturer, pursuant to S4.4.1(a), or in one of the publications described in S4.4.1(b) for its size designation, type and each appropriate inflation pressure. If the maximum load rating for a particular tire size is shown in more than one of the publications described in S4.4.1(b), each tire of that size designation shall have a maximum load rating that is not less than the published maximum load rating, or if there are differing maximum load ratings for the same tire size designation, not less than the lowest published maximum load rating.

OEM already derates the tires AFAIK.. His tire rating is what it says on the side wall.. 2601 @ 44 psi.
Ill find documents supporting this if needed.. After all your not going to fit a 265 70 r 17 on a car are you.

Since this is my first experience with towing I don't have anything to compare it with to know whether or not having 'P' tires is creating a problem. Since I've read so much about the positives of having 'D' or 'E' tires when towing I figure I will put a set on in the near future.

Guess I missed your tires load rating in my reply above but divide the 2601 lb number by 1.1 = 2365 lb capacity for your P tires. A load D or E will stiffen the tire and eliminate that problem...if it was one.

Those P tires at max loads can exhibit sever carcass roll especially with a bumper pull trailer back there.
Also a P tire load capacity on a truck is required by fed regs to be derated by dividing its capacity by 1.1......so if those P tires have a 2400 lb load rating is now 2181 lbs.
A load range D/E will stiffen the tires carcass which eliminates carcass roll. Carcass roll...... is like towing with a half flat tire.
The ibs rating on the sidewall is already derated from the manufacturer. You dont take the lb rating off the side wall and subtract a # from it..
