Thks for the replies. I'll get the truck weighed with full tanks, then get back when I can. Problem is scales are about 100 miles away at least. The pin weight for the TH is listed as 3000Lbs. GVWR 18000Lbs. Dry is 14595Lbs. TH tires are ST235/80R16-E. I'll be under GVWR when traveling as I only have food, clothing, 1200Lb of toys and minimum camping supplies. I have listed weights allowed for my pickup in my OP. Max payload is 4000Lbs. So I figure with pin of 3000Lbs and Air suspension of 5000Lbs shouldn't I be good to tow it as long as I have the load balanced and keep the pin at 3000Lbs? Pickup GAWR is 7000Lbs.
