2011 Ram 3500 SRW 5th wheel capability?

I have an excellent condition 2011 SRW 3500 megacab looking to tow 15.5--16.5K 5th wheel toy hauler (2300-2700lb pin).

I will be using the toy hauler 4-6 times a year 200-1000 mile trips. The truck is used for many other things so DRW isn't practical especially as I live in crowded city.

I was originally thinking I needed to upgrade to 2013 + Ram 2500/3500 SRW to get the right load rating.

In speaking with Ram, they recommend 2014 Ram 2500 or 3500 SRW for the type of trailer I'm trying to tow. Trying to stick to SRW and it is apparently well within it's rated rating.

Capacity rating is as follows...

2013 2500 Mega 3.42 is rated
GVWR 10,000
Payload 2,250
GCWR 25,000
Max Tow 17,080

My current 2011 3500 Mega SRW 3.73 is rated
GVWR 10,100
Payload 2,590
GCWR 21,000
Max Tow 13,350

In studying the difference, the 2013 Ram 2500 has the same frame, 68RFE transmission, and same rear axle (yes, I understand the upgraded frame, etc on 2013 3500 but I'm speaking about the 2013 Ram 2500 which has the same frame).

They have essentially the same braking system and engine power. Only significant difference I found is the tire load rating.
My 2011 17" tires are rated at 3195lb each, the 2013 18" tires are rated at 3640lb each.

Besides the tires, it doesn't make sense that a 2013 Ram 3/4 ton would be rated higher in it's tow rating compared to my 2011 Ram 1 ton.

I prefer to stay with SRW for many reasons and I love my current mint low mileage 2011 3500 megacab SRW, has exhaust brakes which work awesome. I am willing to upgrade the tires, cooling/bags, etc if needed as it is no big deal. I rather go that route than go to 2013+ Ram just to get a silly sticker on the door. I am thinking that with mild upgrades, I should have at least similar or more capable 1 ton tow vehicle than a 2013 Ram 2500.
The huge jump in tow rating form 2013 Ram seems more like marketing trick more than anything.

Perhaps I'm missing something, any thoughts from people with real world experience with SRW 5th wheel towing would be appreciated.

  • The tow ratings or GCWR are bigger because of the different engine and tranny.
    The MY 2013's have more HP and TQ with the added DEF. Also it could very well have a Aisin tranny.
    The GVWR only increased by 100 lbs which explains your frame question. One year Ford increased the brake rotor size by about a quarter inch and upped there GVWR by 1000 lbs :B
    Just me but 16.5K lbs of trailer your going to need a DRW truck or some bigger rubber.
  • Do what you want. This argument will be waged for much longer than I will be alive. Mainly because so many people think they are smarter than the people who designed and certified these vehicles as to their capacities.
  • The thing is, even though the parts look vaguely the same, many things can be very different.
    I would not overload your truck just because a later model has more capacity.
  • With a SRW 2500 or 3500 and a fifth wheel, the limiting factor is can it handle the pin weight plus weight of cargo. Due to there heavy weights, Mega cabs often have low payloads (cargo carrying capacity). You said your payload capacity is 2,590#. Will this be enough to handle the pin weight and other weight you put in the truck? I can't tell because I don't know what fifth wheel toy hauler you are considering. Even more important to me is will the total of the pin weight and other cargo weight on the rear axle (including the weight of the hitch) make the rear axle exceed the rear axle weight rating (RAWR). If it does make it exceed the RAWR, then you have too little truck for that particular trailer. Good luck on your research.
  • Will be watching this discussion -
    I am confused over the differences.
    Need to up grade from 2005 Ram 2500 -
    its been towing it but I feel the need for more strong behind it.
