Does A Weight Distribution Hitch Count Against My Trucks Payload Capacity?

Question:

Hello - does a weight distributing hitch count against my truck payload capacity or as part of the trailer weight? I have a 2025 gmc sierra 1500 baby diesel that can tow a lot, but the truck payload has been my limiting factor in being able to find a towable travel trailer. My payload sticker says 1355 lbs. 435 of that is myself, wife and two dogs. Then hitch weight is gonna be some 800 lbs and I’m hearing the weight of the actual hitch counts too, which puts me right at my limit. Can’t out anything in the bed of the truck. Is that true?

Hey Dave, thanks for reaching out. Yes, the weight of the weight-distribution hitch itself counts against your truck's payload. Your 1,355 lb payload sticker is the number I trust for your specific Sierra, and everything added to the truck comes out of that number: people, dogs, cargo, accessories, the physical weight of the WD hitch, and the trailer's tongue weight. GMC also specifically states that trailer tongue weight is part of the weight the truck is carrying.

Using your numbers, you are definitely getting tight. You have 1,355 lbs available, minus 435 lbs for passengers/dogs, leaving 920 lbs. If the trailer has 800 lbs of actual loaded tongue weight, you are down to 120 lbs before adding the WD hitch. A typical WD setup can easily weigh 70-100 lbs, leaving almost nothing for anything else in the truck. The weight distribution system moves some load from the rear axle toward the truck's front axle and trailer axles, which helps handling and keeps the truck level, but it does not increase the 1,355 lb payload rating.

So your thinking is right: payload, not towing capacity, is your limiting factor. That is very common with well-equipped half-ton trucks. I would shop for the trailer based heavily on its loaded tongue weight, not the advertised dry tongue weight.

What kind of trailer did you have your eye on?
