towing capacity

Hi, I am looking at getting a 5th wheel toy hauler, does anyone know what the towing limits are for a 2006 4x4, SWB, short box truck is?

Thanks,

SMB

You didn't say if it was 2500 , 3500 , SWR or DRW . Other info needed is which engine (HO?) transmission , and rear axle ratio . The maximum would be around 16,0000 lbs.

Sorry, 2500, 5.9, heavy duty, SRW, since I purchased the truck used, how do I find out the gear ratio, and if it is HO?

Thanks, SMB

Scroll down to pages 25 and 26 . Knowing the gear ratio isn't all that critical . Whether it's a 4.10 or 3.93 only varies the rating by 50 lbs.

Also, the hitch weight of a 5th wheel can be 15-20% of the weight of the trailer, even more with a toyhauler if the tanks are full and garage is empty.

Add to that the weight of the hitch assembly and whatever else is in the truck, and you would likely exceed the rear wheel weight rating on a SRW truck with a 5th wheel before you exceed tow rating or gross combined weight rating...

I have the origianal sales brochure that came with my '06 Ram. Here are the figures straight out of the brochure for a SRW, 4x4, Quad cab, auto with 3.73.
payload capaicty is 2090lbs.
towing capacity is 12950 lbs regardless of axle ratio. Only the 3.73 and the 4.10 are listed.
Since the rear axle is the same for the 2500 and 3500, you could change out the factory leaf springs to a increase them to the capacity of the 3500 SRW OR add air bags as I did to my 2500. The max payload on a SRW 3500 short box quad cab 4x4 is 2920lbs. That same increase in paylod due to the heavier spring capacity is added to the 3500 SRW towing capacity it to increase it to 13850lbs.
As far as output, the brochure makes no mention to any option for HO. I believe all the 2006 model year engines are the same: 610 lb-ft of torque at 1600rpm with 325hp.
Hope this helps. PCM

I think there is a typo here, but not sure what it should be. Please clarify.
Thanks.

No typo just my poor explanation. I will try to clarify.

2500 series payload is 2090lbs. 2500 towing capacity is 12950lbs

3500 series payload is 2920lbs. The increase in payload is due to the extra leaf in the rear springs.

The 3500 towing capacity is 13850lbs, 900lbs more than the 2500.

Again, right out of the '06 Ram payload/towing guide. Hope this clarifies. PCM

PCM Thanks for clearing that up. I thought maybe some numbers were missing or transposed.
Thanks again.

Ratings changes from 2006 to 2009

Does anyone know what changes were made to the '09 to increase their towing capacity?

I've got a 2006 2500 short bed, Cummins, manual transmission. Everything I've seen indicates the maximum that I can tow is 12,950. Looking at the '09 2500 it has a towing capacity of 15,650.

My problem is that I've seen a certain 5th wheel which which my wife and I both like and could afford. This 5th wheel has a GVWR of 13,850. Everything I've read indicates I shouldn't tow more than 90% of my trucks max which means nothing heavier than 11,700. Yet, the '09 model could handle this trailer and I'm wondering what Dodge did. e.g. Could I retrofit my truck to handle the weight.

I suspect the answer is either that nobody knows the actual changes or those changes can't be retrofitted. Still I figure it's best to ask since I was already planning on adding the OEM exhaust brake to help slow the beast and that's a $2k item.

Are you sure you're looking at the same specs?

A truck is typically rated to pull more when the trailer is either a goose neck or fifth wheel style. A lot of times that difference is a couple thousand lbs.

Maybe you looked at the bumper pull specs on your '06 and fifth wheel ratings on the '09?

Very good point. I rechecked the numbers from TrailerLife. They make no distinction as if the ratings are for bumper pull or 5th wheel on the Dodge. I happened to look at the Ford's and a F250 shows 12,500 for bumper pull and 15,600 for a 5th wheel. That indicates to me that the Dodge numbers are for bumper pull only.

I'll need to find something official from Dodge for my own piece of mind.
