Unsure of tow capacity....

[Jbgarrison6]

Newbie here. I have a 2017 Ram 2500 6.4 Hemi, 3.73 gears sb, and have towed a 30' tt for the past 5 years. Been very happy with the performance overall, as this is my first Ram I've ever owned. Has pulled this camper very well. Well, we are a family of 6, and we have out grown the camper. So, we have decided to upgrade to a 5'er. I went to the Ram towing guide for my year, and said my set up is rated to pull 12,600. Now, I know that number isn't accurate based on the payload. I calculated it myself by taking the GVWR subtracted from GCWR and came up with 9,800 tow capacity. The 5'er we are looking at weighs 10,600 dry, 13600 GVRW. I know we won't come close to the max cargo capacity for both the camper and the truck, which gives a cushion. I really don't won't to have to pull the trigger on a new truck as I just paid this off back in Feb. So, any thoughts on being able to pull this safely?

12,600 sounds right for towing capacity. Your issue is going to be payload. You probably have around 3000 lbs of payload, give or take a 1000, which is average for a 2500 6.4. Figure 200 lbs for a hitch, plus you and any other persons and cargo in the truck. That's going to limit you to something with around 2000 lbs of pin weight max. And don't go by advertised pin weight, those are dry numbers that don't include propane, batteries or anything you put in the 5th wheel. Not sure your going to find a 5ver that will sleep 6 that you could tow with a 2500.

Need to know the cab and bed you have.

What does the sticker on the door frame say?

Need to know the cab and bed you have.

Definitely not a regular cab if he has a family of 6. Unless the family is following in a separate vehicle. Which might be the case anyways since stuffing 6 people in a crew cab would be interesting in and of itself. LOL Ringling Brothers would love to have a chat!

 

[Jbgarrison6]

Yes it is a crew cab 6 1/2 bed. Yes, if you want your patience tested, try stuffing 6 in a crew cab..

Sticker says 3144 lb payload. 10000 GVWR.

Go to a scale (CAT Scale, junkyard, quarry, ect) and weigh the truck with whatever you take on your trips. Then subtract that from the 10,000 #s. That is your Payload you can add to the truck.
So if your truck weighs in at 8500 you can add 1500#s to the bed. The trailer pin weight and the hitch shouldn't be over 1500#s.
That's not a very big 5th wheel considering pin weight should be 15-25% of the trailer GVW. So that leaves you with about an 8k # GVW 5th wheel trailer with 20% pin weight.

Yeah, go weigh your truck with everything in it that you'd have when towing. Add 200 lbs for a hitch and what you're left with is what you can have for pin weight.

I think you are in 3500 country. Here is why.

As others have said, it is mostly about the weight. The best you can do is load everyone in the truck with all the stuff they carry in the cab plus whatever you carry in the bed when travelling. Get that weight and add about 250 for hitch and subtract this total from Payload Capacity on door jamb and that will give you remaining capacity. I guess you would find about 2100 pounds PC available.

On the trailer, with 6 people you are going to be on high end of trailer pin weight. I would go no less than 20% for your calculations but you may even want to bump up to 25% to be safe (that is where my cousin is with his truck and 5-6 family members when they travel, it all adds up). The 15-20% is just an average for 3-4 people and your situation is definitely above average. All that extra gear for the +2-3 people will push your pin weight. Just to say it, don't try to put more weight behind trailer axles, you will fishtail that rig right off the road.

So for your truck I guestimate a trailer fully loaded of about 8,400 pounds wet weight (meaning fully loaded, leave water and sewer tanks empty while traveling) for your present truck. The math is 2100 pounds PC left after people and hitch divided by 25% = 8,400. By virtue of all this, I would definitely consider a 3500. A gasser will give you about 1k more payload over a diesel and cost less. I have pulled 5th wheels with gassers and was very happy with performance, just stay within specs but depending on trailer you end up with, a diesel may be needed due to gcwr.

Good luck.
