Tow Capacity for 1999 Dodge 3500 Dually

I've got 99 Dodge 3500 DRW Diesel 5 speed manual - door states GVWR of 10,500. Truck currently has 15k Reese 5th wheel hitch already. What is the maximum weight I should safely pull with a 5er?

We are considering going full time and are looking at our options. We like the DRV Mobile Suites but we are concerned they are too heavy for the truck we currently have. Truck was pulling a Sabre 5er (9,825 lbs dry) - previous owners were parking 6 months out of the year. We are planning on traveling the US and moving about once a month.

I don't have data for the 1999, but the 2002 2nd generation 3500 had a GCWR of 21,500 lbs for the 245/505 Cummins HO/6 speed with 4.10 gears and 20,000 lbs for the 245/505 HO Cummins/6 speed with 3.54 gears - and that's with 4 wheel disc brakes. "Non-HO" Cummins trucks were lower. Therefore, even being very generous, it would probably be safe to assume that your 1999 has a GCWR of 20,000 lbs or less, most likely less.

But being generous, at 20,000 lbs GCWR, you're probably looking at a wet, loaded truck weight approaching 8,000 lbs. 20,000 - 8,000 leaves 12,000 lbs towing capacity, and a 12,000 lb 5th wheel would have a pin weight of ~2,400 lbs (20% of total weight). 8,000 lbs + 2,400 lbs = 10,400 lbs, right at your 10,500 GVWR limit.

Will it pull more? Yes. Will it pull more without exceeding one or more manufacturer's ratings? No. Will it pull a Mobile Suites? Unless you're looking at a very early, very short unit, I wouldn't. Our 2004 36' Mobile Suites has a GVWR of 16,000 lbs - newer ones are even heavier.
