I have a 2004 chev 3500 SRW pickup. In the manual, it lists the GVW, GCWR and the trailer tow capacity for a tag hitch.

I need to know what the legal capacity would be for a gooseneck. Can I assume 15% pin load, and just max the GVW of the truck without going over the GCWR?

Anybody?

I do not have a hitch or trailer yet, I want to know how big I can go an be legal.

The truck is rated for a 9600lb tag trailer. It is a 3500 SRW crew cab with 6.0 gas. The truck has 9900LB GVWR and I think the GCWR is around 21,000.

If the truck weighs 7000 and has a 9900 GVWR then I have a 2900lb payload cap. If the gooseneck is loaded with 15% pin load, then the trailer would weigh 19333LB That puts me over the GCWR


What I need to know, is if the Goosneck towing capacity is in fact calculated by figuring out the load transfered to the truck and not exceeding GVWR and GCWR.

Its hard to get a hitch for a pickup for over 12500lb .If you pull a 14000lb trailer you should have a goose neck. I would not want to pull 12000lbs on a pickup every day . I was burning up rubber like mad . If your truck is 10000lbs gvw you could pull 16000lb trailer if your truck is rated for it . At 12000 lbs you really need DRW .

you would need a 3500,, which he has, why do you need a drw?

Load on the truck can not exceed the truck's GVWR. That means truck weight plus tongue weight plus other loads in the truck including people and fuel. Next limit is weight ratings of your axles and tires. You might be under on the GVWR but over on the weight of the rear/front axle. Then you have to look at pin ratings. Then your trailer ratings. Again you can't exceed your trailer's GVWR or axle and tire ratings. Then you have your GCWR. The max that the combo can weigh. And finally your driver's license and state laws. And as for the GCWR, you can be in trouble with an empty trailer as it is by capacity and not just by what it really weighs. A 10 ton rated trailer and a 9600 lb rated truck would be over the GCWR of 21000.

Examples:
I have a 3500 Ext cab DRW 2001 Silverado. Truck is rated at 11,400 and GCWR of 21,500. Utility trailer is rated at 7000 lbs. Coupler is rated at 10K. This would all be legal if none of the factors are exceeded.

Same truck with the 39' travel trailer rated a 10K gives you a 100 pound leeway on the GCWR. Getting real close, but still legal.

Same truck with an empty 15K equipment trailer. Doesn't weigh more than the ratings but would be illegal as it exceeds the GCWR.

Just for clarification, GCWR means nothing legally! It only will hurt your warranty. The only piece of information that a DOT officer is going to look at is your door tag. The weights you need to stay in are the following: GVW (9900 in your case) individual axle ratings, and tire ratings. As long as you are not over on any of those you can pull any weight trailer you want. If you are using it commercially then you will, at least in Michigan, an elected GVW plate. I have a SRW 3500 plated for 24k. I can load that truck over the GVW of the truck (mine is a 9200) to say 11k. As long as I am not over on my tires or axles I am fine. I could plate it for 42k and pull a semi trailer as long as I am not over on tire or axle ratings and not combined over my plated weight.
