Ram 2500

I've got a 2015 RAM 2500 6.4 HEMI GAS

In your opinion, (and I have learned to trust these opinions) what should be the max weight 5th or TT I should pull without straining my truck too much. Currently pulling Jayco 29RKS with no problem. All charts say max is 13,200 but have been told not to go that max amount.
Thank you all

Don't exceed the GVW or the GCWR, and you will be fine. The limits are there because the truck can pull them and not strain the components.

I don't know who told you not to go near the maximum, but I believe they are wrong. If they told you not to exceed the maximum, they would be right, but the truck should do up to the max without undue damage due to "strain" (?).

Reason not to go to that mfg. published max tow is because you will more tan likely exceed trucks GCWR and/or GVWR before reaching that max tow number.

Payload is the first number that needs to be considered....especially with 5th wheel because pin wet is carried by trucks rear axle.
Payload number should be on 'yellow sticker' in door jam

You need to get truck weighed 'camp ready' (you, passengers, fuel, and stuff in truck cab and stuff in truck bed).
Compare the weight numbers (front axle/rear axle/total) against trucks GVWR, FAWR and RAWR.
Subtract total from GVWR---what do you have left before reaching GVWR?
Subtract rear axle weight from RAWR-----what do you have left before reaching RAWR (Actual payload)
Check rear tire max load rating at max psi on sidewall.......how much left before reaching max load rating? (again ----actual payload) tires can be equal or less than RAWR

Now you have real world numbers to work with.

Then using a 'guesstimation' figure 5th wheel pin weight at 20% of the 5vrs GVWR
(13,200# 5vr----20%-----2640# wet pin weight..........do you have payload to carry that weight)
Using a 'guesstimation' figure TT tongue weight at 15%

It's all about what total weight you can carry w/o exceeding trucks ratings.
Your trucks GVWR is probably 10,000#
RAWR is probably 6000#

12,000# GVWR 5vr should fit within trucks ratings

Over on ramforum there are a number of users pulling up high quite happily- even with 3.73s.

On other forums I visit (trucks and RVs) many guys go by no more than 80% of maximum trailer weight. That logic seems to fit what OB said as well.

Actually that is not what I posted.

I have no problem towing at trucks MAX ratings........not mfg. magical published numbers which are not real world.

I use trucks GVWR, Axle weight ratings, tire load ratings and GCWR to tow by.

I use 20% of trailers GVWR to guesstimate what wet pin wet would be......not as a deduction of trailers GVWR (80% figure)

I don't think you'll break it towing max payload and tow rating. IMO it's about how you like to tow. I for one don't like the constant back and forth shifting. If the tranny can be locked into a gear where it stays there most of the time then that weight would be what I'd tow. If the trannies shifting at the 1st overpass then I feel its past what I'd enjoy towing all day long. If your foots buried in the floorboard when climbing a mtn pass, then it's probably too much.

This, of course, is an opinion. Commercial truck drivers spend most of their mtn pass climbing with their accelerator foot pushed all the way on the floor, and downshifting gears to find the one that can pull the hill. And those trucks are carrying at or less than their *legal* weight limits, which can be lower than their vehicle components maximum weight rating.

Yes, commercial trucks are designed to last longer pulling all that weight than a pickup truck, but the example is still sound. Comfort is very different from ability, and the world is comfortable enough IMO.

I had a 03 Ram with the 5.7 hemi. Towed a 7K TT to Yellowstone from So Cal. There were many grades I had the truck at close to 5K RPM and the foot close to the floor if not on it. When I got home I sold the truck to my son and bought a 5.9 diesel. The new 6.4 hemi in the 2500 is a great combo but be ready to really work it if you tow at 10K and grades of altitude. To each their own.

A gas truck will do fine at, near, or slightly over it's ratings. The trouble is what we are used to nowadays in regards to the speed and horsepower of vehicals. With modern diesels everyone is used to towing 15k uphill doing 80mph. That requires no skill and no shifting. There was a time when people did more with less because they knew how to run a truck. We live in a time where having a truck drop below 55mph on a hill is such and inconvenience it requires a new truck that will do it without dropping below 70.

If it were my truck an 8-11k TT or fifth wheel would be what I'm looking for.

A SRW 3/4 gasoline powered Truck is limited by your tolerance for noisy uncomfortable towing. If you want an easy tow stay light with your trailer. If you want to test your tolerance max out the truck.

I have had people tell me towing a 5,000lb boat with a 6 cylinder SUV that you could not tell the boat was back. I know that have lie.

You have to sift thru all the bogus posts and decide yourself your tolerance level.

I didn't say it was hard on it, I meant that who likes to tow that way? No one wants to tow such a heavy load that requires their foot pasted to the floor board. If you have to because of work then so be it. But most recreational towers would rather not. I've been in that situation with a gasser. Not really any fun when you have to floor it to just keep from slowing down up a mtn pass. I was not overloaded on any rated weight, just under powered.
