Not a concise article, just a snippet of some of the trucks.

All seemed logical to me. I always thought 5th wheel towing numbers were ridiclously inflated. On some models it appears they were. Having to factor in the 20% load on the truck payload brings those numbers to earth on the marginal configurations.

i wonder if the weight police will be disappointed with the small drop in tow rating on GM vehicles. Personally about what i guessed, most configurations have very little change.

Wouldn't it be nice if someone went back and applied the SAE J2807 standard to previous year models. Say someone that publishes towing guides.

Might have an interesting effect on the used truck market.

BTW did i read that right, 1-tons really can handle bigger 5ers?

From the article:

"The largest drop in tow ratings came in selected 2500 models with 5th-wheel and gooseneck hitches. For example, a two-wheel-drive regular-cab long bed with the Duramax diesel and 3.73:1 axle was rated at 17,800 pounds using a 5th-wheel hitch. For 2013, the rating drops to 14,400 pounds. A four-wheel-drive Extended Cab long bed with the diesel and a 3.73:1 axle saw its rating drop from 15,700 pounds to 10,900 pounds."

“For 5th-wheel towing, SAE J2807 assumes that 20 percent of the trailer weight is on the kingpin,” Perelli said. “Previous calculations consider 17 percent with the understanding that the GVWR and RGAWR would not be exceeded. This change, in addition to the additional mass considered above for the additional passenger, optional content and aftermarket trailer hitch equipment can have a significant effect on the new calculated trailer weight ratings for 5th-wheel trailers.”

The engineers finally win one over the marketing execs. Who would have thought that day would ever come, certainly not me. Of course this is forced on them, not by choice.

GM, and Toyota have taken the lead on this. Will be interesting to see how it affects the rest of the industry.

Look at the fifth pic: you can see the entire frame. The body is mounted at least 5" too high! No wonder there's so dang much frontal area. I still say don't choose your rig based on styling, but this further reinforces my willingness to correct whatever's not right about a new vehicle, the first day you get it home from the stealership. And fixing that, I'd start in the first 2 seconds. Fix that, you'd probably no longer need the airdam!
Moving on, still no gooseneck ratings for 1500s, that should've been added. Well actually, it should've been added in '90 when the 454SS debuted.

Since SAE Towing standards apply only to 13,000 GVW and below.

Expect to see a monster truck with a 13,001 lb GVW that can tow an incredible number.

Still think they allowed some leeway to the manufacturers. Too much of a drop would make potential buyers wary of the manufacturers products.
Still a 4,800lb drop is a rather big "mistake" too make?
