How's this combo

A truck at a local dealer was a 2500 CC 4X4 with 6.4l long horn with other options, door sticker showed just over 3k payload. The truck I'm wanting is similar less 4X4 has a payload of 3500 lbs.

Check! Sounds like a good match then. That 6.4L is strong!

2014 Ram 2500 4x2, Laramie CC, shortbox 6.4L Gas, 4.10 Gear
Payload 3490
Towing 15,820

Fifth wheel
KZ Durango D336RE
Dry weight 10,070 (10,400 actual weight as seen at local RV show)
Dry Hitch 1,830
GVWR 12,500
Length 34' 9"

Going by GVWR (20% x 12,500) = 2500 Pin weight

Looks by the numbers that I should be good. What am I missing? I was initially looking at a 1 Ton Ram Gas but I only gain 490lbs payload (3980 vs 3490) and I'd like to get the 2500 due to the coil spring suspension. The truck will be my daily driver.

About the only thing that I would say- is to watch the payload of the truck.

1) Check the actual truck that you're buying. My available payload is slightly lower than the advertised payload for a similarly equiped truck (per the Ram Body Builder) due to the options that we picked for it.

2) Give yourself conservative estimates for occupants, stuff you carry, stuff you'll add to the truck (my super cool bed cover is 100+ pounds), your hitch, etc. It adds up quick (my family of 4, our truck changes, hitch and all weigh about 1,200 pounds).

I think your pin weight estimate is spot on. The dry pin weight percentage is about 18%- that usually goes up a couple of points, so planning for 20% is realistic. With only 2,500 pounds of cargo carrying capacity in the fifth wheel, you're likely going to be near GVWR when all is said and done.

Here's a couple of handy little calculators that may help:

I just went to the North American International Auto Show yesterday. I saw a 2014 Ram 2500 Laramie Long Horn diesel crew cab 4WD with 1500 pounds of payload! I cannot remember what the 6.4L truck had. Just verify the as equipped payload when you are kicking tires on the truck you want. Look for this sticker when you open the driver's door:

Interesting. Just looked at the rambodybuilder.com site and that combination (with a longbed) listed 1940 pounds payload with the diesel, 2840 pounds with 6.4.

Someone posted a picture on ramfourmz.com of his 2014 2500 hooked to a very large boat with 1000lb tongue weight. Truck still looked level. It would be nice to hear from someone who has put 2000lb + on their truck.

Has anyone seen one of these trucks with the coil spring suspension hitched to a trailer?

Well, to give a direct contrast to a 1-ton, the payload rating for my specific truck is 3,800 lbs. Basically the same truck as you're posting, only difference is I'm Diesel and I have a 4x4. So in my eyes, you're really not that far off from a 1-ton. I doubt you'll really miss those 400 lbs.

Sounds very good to me. Enjoy the toys!

I wouldn't. Get a 3500 and quit worrying
