Max Payload vs. Pin Weight (Ford, Ram, Chevy)

Hi,
I recently bought a new 5th wheel and truck to tow it. I got a 40 foot Open Range with a 2500 pound pin weight.

I was looking at fairly loaded SRW long bed diesels from Ford, Chevy and Ram. I ended up getting the Ram due to the much higher payload. The Fords and Chevys that I was looking at had max payloads (from the door sticker) around 3400 pounds, while the similarly equipped Ram had a pay load of 4200 pounds. My thought was that with the camper and truck fully loaded I would be pushing up against the max payload of the Chevy and Ford (even though I liked them a bit better).

So my setup now, even when fully loaded, will provide me close to 1000 pounds of margin I would guess. Theoretically should my truck do a better job of towing my trailer given that I am significantly below the max payload vs the Chevy or Ford that would be right up near their max? I would guess that would be the case from a logical perspective.

My other question is what would make there be such a big difference in payload between the Ford/Chevy and the Ram? For similarly equipped models (and all long bed, quad cab diesels with automatic transmissions) the difference is about 800 pounds. That is not a small difference. What would be so drastically different with the Ram to justify such a higher rating? Is there something inherint in their design (solid front axel for instance) that makes it more capable of hauling more weight? I assume that the three trucks are all rated against the same standards.


Thanks

  • My 2017, 3500, diesel, Auto trans, CC, long bed, 4x4, SRW Ram has a payload sticker of 4365 so no it doesn't have to be a 2wd gas setup to get that.

    The tires are rated at 3640lbs.

    If I recall my empty weight on the rear is along the lines of 3500lbs I have a tool box (200lbs), a headache rack (150lbs) and includes my b&w hitch (150lbs), and a b&w hidden gooseneck mount (75lbs). The toolbox and rack some of that weight is on the front axle since they are directly behind the cab.

    Real question is which 5vr does he have as they have 5 or 6 different lines some are much lighter than others. If the pin weight is going to be 3200lbs as previously suggested could certainly be close or over. If he has taken into account the added pin weight and added to the brochure spec already then he would be fine.

    However you didnt ask about those questions and regardless of all that I have no idea why the other brands would have so much less payload, 3400 does seem light to me. As far as tow ability I doubt you will see much difference while towing. Hp is HP, torque is torque, braking is braking and in those regards they are pretty similar. Unloaded you may find the higher payload truck rides a bit stiffer and maybe not. As you put it logically it would stand to reason that it would fare better if it wasn't working at max capacity but seems logic falls out the window many times. I am not sure I would expect any real difference in capabilities beyond the payload factor.
  • Since you have already spent the money, load your rig and scale it. That will put you in the 1% that actually (maybe 10%) know the weights. Then hit the road for a while, and see what you think. Don't waste metal capacity with a guess, when for less than $20 you can know.
  • OP has to have a 3500, to get that much payload. The 2500 would just be wt of truck as it left factory minus the class 2 10,000 GVWR limit. The rear axle wt ratings should be similar between the 350/3500 models. The Ram may have a little higher GVWR on their 3500s? In any case, the OP made a good choice for a diesel truck, if it can handle the actual loaded pin wt, which will be much more than the 2500 lbs mentioned.

  • OH WOW! Good luck with this setup.
    The one OR I looked at has a GVWR over 16,000 pounds. That could translate to over 3200 pounds using the basic 20% rule. Your going to be overloading tires before you get done loading that trailer. Of course that means exceeding the mfg GVWR numbers. With a fifth wheel tow rating is meaningless. All trucks can TOW far more than they can carry.
  • 2500# pin??? Is that advertised unloaded?

    What was the rear axle rating of each, also did you get a 2500 or 3500?

    With a 5er you are using almost 0% of your front axle capacity. It's all about what your rear axle capacity is.
  • Not sure what exactly you have, but as far as I know for that kind of payload a Ram has to be a gas engine, not a Diesel. IIRC the max payload on a Diesel is a little below 3200lbs.
