Ok lets see, the truck is a 2003, the trailer is a 2008. It has the older 7.3L diesel (last year this was available). It is 4-wheel drive with the Fx4 package. The suspension is stock (no lift) with the exception of Firestone air bladders which I run at the minimum pressure of 5psi while using a WD hitch as per both Husky and Firestone recommendations. The manual says that with my configuration I have a max trailer weight of 12,500 lbs. It has Michelin LTX M/S2 load range "E" tires that I run with 80 PSI while towing.
I don't remember what tires the trailer has on it (it's at storage right now) but they are 15 inch trailer tires run at 60 PSI. Triple axle
I have weighed the trailer and it is 10,180 LBS as is, before water, food, clothes etc. The truck weighs 7,448 LBS with a full tank of diesel, camper shell and me in it.
I have a tunge weight scale and it is right around 1,100 LBS. I don't remember the exact measurement but it is right around there.
According to all of that info I should be within specs for both the trailer (which has a max loaded weight of 12,300 LBS) and the truck (max trailer weight of 12,500 and max GCWR of 20,000 LBS).
The sticker on the door frame of the truck says I have a GVWR of 8,800 LBS so if I understand that correctly that would be the weight of the truck and the tongue weight (7,440 LBS + 1,100 LBS = 8,540 LBS) leaves me 260 LBS for passengers and added tongue weight (not much but still under).
I think that answers all the questions.
Thanks for your help.
