Towing heavy trailer with a 3/4 ton
 
We have a 2008 Ram 2500 diesel. In great shape with ow mileage. It tows our 34 footer 9900# easy. Dodge says the towing capacity of the Ram is 12,800#. We are thinking about a 5th wheel SOB for full timing. Looking for advice on towing above the 12,800 factory spec. Any modifications to increase towing capacity? Air suspension?

Time for a new 1 ton.

Suspension is only part of the equation. You still have to be able to stop that rig. Axle bearings might seize. Tires or rims can fail. All sorts of parts are “rated” for capacity.
It’s my opinion that air suspension does exactly nothing to increase towing capacity. It will, however, help you level an overloaded truck.

I have faced this situation a couple of times. IMO there is no good answer to this question. Time to have "the talk" with DW about upgrading the tow vehicle.

Overload is overloaded.. 1 ton is the answer

There are ways to do it. This is probably not the best place to ask.

Spot on. The Ram Cummins forum would be a good place to start.



For my year/model, '06 3500 SRW Quad Auto, my tow capacity is 14,400#. In that year the only difference between a 2500 and a 3500 is one leaf spring. I towed a 15,000# fifth wheel from Florida to Alaska and back, 17,000 tow miles total, without as much as a hick-up.


I'd be interested to hear what your setup in truck wise to see where it ended up with that tow rating but again, this probably isn't the best forum to has that out.

I would not do something stupid like going way over the 12,800 pound capacity as quoted by Dodge, but might like to push it a thousand pounds or so. I wonder if the manufacturers recommended tow capacity is somewhat arbitrary.

The penny pinches for the manufacturers have a lot of say in tow rating. Take a '93 Dodge 250 with Cummins & a 3.55 rear axle.
With the 4 speed automatic transmission the GCWR rating is 12,000 lbs
Add a auxiliary transmission cooler and the rating goes up to 14,000 lbs
If it has a manual 5 speed the rating is 16,000 lbs
One of their biggest concerns is if the truck will get through the warranty period without breaking.

The Dodge diesel forum that I used to frequent has a forum for towing. I think you are going to have to study up and see what limits your model.

Suspension is a small part of the equation when considering towing capacity. Another issue not mentioned is going to be your cargo capacity and rear axle weight ratings. This takes into account driveline capacities, braking, frame strength, suspension, tires, etc. When you get into the larger 5th wheels they can have heavy pin weights, that by themselves, will exceed payload capacities of a 3/4 ton. Our former Mobile Suites had a loaded pin weight around 4000#s. Had to go straight to a 1 ton dually. And don't pay any attention to published pin weights or cargo capacities in the brochures. Know your specific trucks specs and weigh the trailer at the scales for an accurate pin weight so you know what you are working with in determining if your 3/4 ton is up for the task.
