Show us a picture of the truck (sideview). I can not believe your truck is not squatting much. You have way more pin weight than a 3//4 ton should. Your truck loaded weighs 12280! You've got about 3800 pin weight if I added correctly!

I will take a picture of my truck when I get home from work, but it wont be hooked up to the trailer. My truck does squat when its all hooked up, it actually sits a little lower in the back. And because of that I have thought about getting air bags on the rear end to eliminate that. As far as the pin weight im not sure how to calculate that, but with what you calculated at 3800 for pin weight I would still be within the specs. With the current 2500HD trucks with the diesel engine it permits towing up to 17,500 lb. Maximum payload with the 2500HD in stock configuration is 4192 so allowing for a 200 lb. max king pin weight it can handle a 5th-wheel weighing in at 15,968 "wet" or fully loaded.

Tires are your limit.

Obtaining your pin weight is simple. Weigh your trucks rear axle, with everything in it ready for for towing. Then weigh your truck with 5er hooked up the same way. Subtract 1st from 2nd.
You cannot rely upon mfgrs. figures, use this 5th wheel weight calculator to obtain the exact numbers.

Here is a picture of my truck, but like i said its not hooked up to my truck. My trucks rear end does squat down when its all hooked up. Its a little lower than the front but I checked the rear axle to make sure the rubber stops were not sitting on my axle and they weren't, the rubber stops still look brand new.

Sorry to be the bearer of more bad news but you have a overloaded 2500 truck. Your loaded drive axle is at 6920 lbs vs a 6500 RAWR/tire/wheel and rear suspension so its not surprising the truck doesn't handle well. Your trucks FAWR and RAWR numbers are on the certification placard on the drivers side door post.

This isn't your particular very heavy 4x4 crew cab diesel 2500 trucks payload. See your yellow tire placard on the door post for your trucks mfg recommended payload.
As Glenn West says your axle/tire rating will determine your trucks actual payload.

Ram may give your truck a 17k tow rating but your particular 2500 truck simply doesn't have enough tire/wheel and rear suspension for carrying your present loads. If you need help understanding Rams Body Builders Guide specs for your particular trucks ratings we can help you with that.

Air bags are needed in your case. If you have 3195 lb 17" wheel and tires you need to upgrade them to 3500-3600 lb 18" tires and wheels.

I know your stressed over the nose high trailer issue and now a overload issue. Many Dodge/Ram 4x4 owners seek help from their truck dealers. At one time shorter rear suspension blocks were a manufactures fix for the rear of a tall 4x4 truck.

I have a stock 20" rim and I just looked at the max load rating on my BFG tires and it said 3860 at 80PSI. with all the new info I am going to get air bags on the rear end. I didn't see the sticker where it says the payload capacity, but I looked at that one too and it said 2108lbs, which I think is a little ridiculous for a HD truck. You would think for the amount on money I paid for it the payload would be more. Hopefully when I put the air bags on the rear end it will eliminate the payload issue. Still have to figure out what to do about the nose high issue. Thank you all for the help.
