I'll see if this works!

I am trying to find exactly what size 5th wheel I can handle safety.

I have a 1999 Dodge 5.7 Cumming Diesel Cub Cap long bed.

On the driver's door is says: GVWR 8800 Front GAWR 4410 Rear 6084

Weighted empty at scale: Front axle 3880 Rear 2780 Total weight= 6540.

To figure out what size of 5th wheel I can safety tow?

GHWR or Pin weight: 8800 lbs X .25 or 25% = 2200 lbs.

I tried looking up the GCWR which I think is 15,000 for this truck.

So for example: A Montana 293RK stick says: Payload 2,080 Loaded Trailer 8,320-10,400

I take 10,400 lbs for the tailor and multiply .25 which equals, 2,600 lbs. Looks like this 5th wheel is too heavy. Right or wrong.

I don't see to many people ever say what their rear end ratios are and that is very important as to how much you can tow.

F-250 with V-10, 6 speed manual and 3:73 rears.

I'm having trouble understanding the RV Tow Check 2.0 calculator. I am looking to upgrade both truck and a 5ver and want to know what the correct towing capacity is of any new truck I buy before shopping for the trailer. I'm looking at a 2015 F250, 4x2, crew cab, 6.7l Turbo diesel with a 3.73. I find the GCWR is 31,900, the GVWR is 9900, I set the GVW at 6800 (curb wt.), gear and cargo at 500 and passengers at 500. At a 20% pin weight the calculator shows such a truck would have a 9500 lb. towing capacity for a fifth wheel. Am I interpreting this right? That seems low for what I have observed on the road and its well below Ford's published 23,600 lb maximum loaded 5th wheel weight for such a truck in their towing guide. Thanks in advance.

If you included the hitch system with the 500 pounds of cargo, and also checked the 5th wheel hitch option, that would be incorrect. But if you meant 1000 pounds of cargo and passengers, plus selecting the hitch, 9500 pounds towing capacity @20% is correct.

The GVWR is the limiting the towing capacity and that is very common with 3/4 ton trucks. The engine and transmission is not any different than the 1 ton trucks. But it could be the springs or gear ratio or the brakes or axle or wheels or any combination that keeps the 3/4 ton from handling much pin weight. There are a lot of 3/4 tons that are towing 5th wheels while exceeding GVWR and GAWR as shown on the certification label.

While they may be exceeding their GVWR, many are still well with in the GRAWR for their TV.
I know this is how I tow, the 250/2500's fill a registration loophole in many states by keeping the GVWR at 10,000# or less, equals hundreds of dollars in registration fees.
