SAE J2807 Recommend tow ratings - ratings change?

[RollingDownTheHighway]

I'm looking to upgrade my '14 1500 Silverado to a 2500 and I'm looking at the tow ratings on both the Chevy and GMC and the '16 are towing less then a '15. Has the tow rating process change? Am I missing something?


this if for GMC, but Chevy is the same:
GMC Pressroom - United States - 2016

Wow, that's almost a 3,000lb difference between a '16 and my '11 2500.

[RollingDownTheHighway]

yeah I know, I'm talking to Chevy right now and they're telling me that only the 2wd Duramax reg cab long bed can tow #17,9.

The dbl cab diesel, 4wd can tow #16k

[AquaMan]

My '11 2500 Crew 4x4 8' bed was rated at 15,500 or 15,700, and the rest of the specs are almost identical. I believe my payload was 2486lbs. where the '16 is 2423.

Tow ratings in this case doesn't mean much since the payload of 16k would 3200 lbs at 20% and 4000 lbs at 25% pin weight which is way over the payload of 2500 diesel.

2500 HD

My 5er on the scales weights 11380 lbs with 2740 pin weight. Added the 700 lbs for the hitch, people and misc I have in the truck it would take 3440 lbs of payload to stay within specs.

We may have to change our 5'er options or go to a 3500 instead.

My 42' Sierra had a 16% pin weight(14k and 2300 pin) and pulled like a dream. There is a big difference between trailers and not all of them fall in the generalized "ideal" weight. That said, I also think 16k is too much for 2500. I pulled the Sierra for 2 seasons with a 2500 and while it did fine for me, it may have been too much for someone else. I switched to a 3500 which was a much easier haul.

I agree with this:

my TT now grosses out at 9700 and we looked at another TT manufacture with the same floorplan but aluminum siding and it grossed out at 11k.

I just may get the 3500 Crew Cab

Sorry, I was talking about "ideal pin weight" percentages. But I do know what you mean.

I agree with floor plans weight have different pin weights. A rear kitchen will have a lower pin weight then center kitchen. Toy Haulers are all of the place in pin weights. Also the manufacture specs are also suspect. My dry specs were 9500 lbs and 1980 pin weight. I added less than 1200 lbs and the pin weight jumped close to 800 lbs which shouldn't have happened since most the weight was in the center kitchen that is over the wheels.

I do think it is smart to got to 3500 but still watch the payload. Some 3500 have less payload then some 2500's. It all depends on the GVWR is 10,000 lbs or 11,500 lbs.

We're looking at a few 5'ers with the front living room and really like those but we saw some other ones we like at the RV show we went to this past weekend. We really like the montana 5'ers

I looked at some front living room and like the layout also. At the time I had Chevy 2500HD Diesel and couldn't find one that fit into my payload specs.
I purchased the Forest River and found that I was 800 lbs over weight and less than 200 lbs of max axle weights so I traded for the F350.

We had a Cougar which is a Keystone product and didn't have any trouble with it and would hesitate getting a Montana if I like the floor plan.

[GOTTOYS]

Minimal if any, cost difference between a 2500 and a 3500. The license cost here in MN is about 25% of what it cost to license a 2500 because the 3500 is licensed as a truck and the rate is based on the GVW. vs: licensing a 2500 as a passenger veh and paying based on the value. I'm very happy that I traded up to a 3500. Ride is the same, not much difference that I can see other than it will haul more...

this if for GMC, but Chevy is the same:
GMC Pressroom - United States - 2016

Before J2807 standards manufacturers did all kinds of shady stuff to claim tow numbers. Removing spare tire, bumpers, tailgate, even center console in some cases.

"Ram has certified its 2014 and 2015 Ram 2500 and 3500 products to J2807, but General Motors has not done the same with its 2015 Chevrolet and GMC 2500 and 3500 HD models."

If I'm correct the J2807 deals with towing only and doesn't take payload requirements as part of J2807.

Yep, GM is using J2807 on the HD's for the 16 model year, and Ford is not using it for the 250 and above until 17. I think Ford is waiting so they can recoup numbers when they go to aluminum bodies. That was all announced awhile ago. The games will continue, just different rules is all.

I believe you are.
