Suggestion

Step away from the brochures. You are confusing yourself with all the charts. Please, just ignore all the info about max towing, because you won't get there, and if you go by it, you will exceed your trucks capacities.

Weigh your truck with you and your wife in it, and a full tank of gas. Get separate weights for front and rear axle.

GVWR is 10,000 for your truck. Subtract your actual weight from 10,000 That is your remaining payload after you, wife, and gas. Some of us believe 3/4 tons are artificially capped at 10,000 GVWR. Others won't take a Big Mac to go if it puts them over 10K. Your payload should be on the yellow sticker on your door jamb. That's the payload for YOUR truck, not a brochure number. Which is what you need.

Payload is a good number to have. But, for 5ers, many of us use the axle weight as the critical number to follow. Even on my 3500, I exceed my payload by 10lbs, but have more than enough axle capacity for my 5er.

After you weigh the truck, you will have a rear axle weight. Look on door jam for GAWR rear. It will should say 6000. Subtract your rear axle weight that you got at the scale, from 6000. That is the MAX pin weight you can handle with your truck.

Generally speaking, you should use the trailers GVWR x 25% to estimate a trailers pin weight. If you find a trailer you like, look for the GVWR sticker on the drivers corner of the 5er. Multiply that by .25 to get your estimated pin weight.

Don't forget to take into consideration the weight of the hitch. 2-300 lbs depending on what hitch you get.

If you cannot weigh your truck, the previous chart can help. Looks like axle weight is neighborhood of 2900lbs. I would go with 3000. 6000-3000 is 3000 remaining axle capacity. Estimate 300 lbs for hitch (to be safe). Your pin weight cannot exceed that number (2700), which puts you in a 12,000 lb 5er category at best.

There is no way I could see you towing a 16,000 5er with your truck. It should/will likely have 3500-4000 pin weight.

Mike, thanks. Yup I have a much better understanding where I need to be. Like I said, the first post was a baseline for ideas. I know now where I need to be looking, and there are plenty to choose from in my category. Thanks!

So there are two stickers. One with weights, one with tires.
The one with weights says GAWR FRONT 6000#, GAWR REAR 6500# GVWR is 10,000#

The one with Tire info says Combined weight of occupants and cargo should never exceed 1,970#

I ooked on the sidewall of the tire and it says 3649# rating

Which one do I go by?

After weighing your truck, full fuel, people, gear, and adding 200 lbs for future hitch, if not already installed, look at wt of rear axle. If it shows 3,500, you have 3,000 lbs still available for hitch and pin wt.

A FW pin adds very little, likely less than 100 lbs to the front axle, towing a FW you can handle.

I would not be over concerned about the 10K GVWR as that is a class 2 limitation for license, registration. The 1,970 number is the weight of your truck, as it left the factory, subtracted from the 10K class 2 rating.

For safety and legal considerations you go by the trucks makers 6500 RAWR as it carries all the weight in the bed.
The RAWR includes the lessor of the tire/wheel/rear spring pack and the rear whole rear assembly.
Looking at Rams body builders guide shows the rear spring pack and the wheels have the lessor ratings.
The tires have a 3649 lb capacity for a good reserve.
The axle assy itself is a AAM 11.5" and has around 10700 lb rating and is the same one used in the 3500 SRW truck so your not even close there..

Anywayz simply drop by a set of CAT scales and weigh the trucks front and rear axles with attention to the trucks rear axle which may weigh in the 3000-3100 lb range leaving over 3000 lbs for a in the bed payload. Scaled numbers tells the tale.

The 17k lb trailer tow rating is real as it covers all types on trailers (not just rv trailers).

Triaxle trailers can have less pin weight.

Equipment or flatdeck trailers farm and ranch implement trailers can be loaded with less hitch weight to stay within the trucks 6500 RAWR.

A 17k lb 5th wheel trailer is best handled by the 3500 DRW with those big 9750 RAWR numbers.

1970 is your payload
6500 axle weight is good. Thought it was only 6000, so now you have some more room to play with.

Tire weight exceeds axle rating, that's good too.

As others said, it's best to get actual weight from truck scale, then you know exactly how much weight you have to spare.

My Pullrite slider hitch weighs 300lbs. You will probably be in the neighborhood of 2800-3000lb pin weight available when done. Still in the 12K 5er category.

Remember if you have a spray in bedliner and/or a bed cover, those add directly to rear axle weight

Not exactly. Your liner and cover, like everything else on the truck, add to the weight of truck, and reduce the capacity you have available for pin weight, but do not change pin weight.

Yet another person learns a bit the hard way that diesel 250/2500's are not the best for towing medium to larger 5th wheels. The 3500 model of the same truck has a 7K RGAWR and a 12,300 GVWR, and a more capable rear suspension.

OP, you can air bag it on the rear axle and pretend that it is a 3500. Enjoy!

When we bought our last 5th wheel we looked for one with a lighter dry pin weight and choose our Bighorn 3575el for its 2435 dry pin weight. Full timing with trailer at close to 16K truck at 8900 ready to tow, we were 40 lbs over the SB 11,700 pound GVWR and under on rear axle at 6700+.

The combined weight was 24,500 and with the Aisin tranny with it's lower 1st and 2nd gear ratios it worked great. Chris
