Re: C30 capacities???

I have seen a VIN plate that list "*Maximum Capability" GVW 14,000....

*Refer to owner's manual for equipment required for intermediate or maximun gvw ratings, and for other loading information, including tire inflation

...with a trailer...?

Right, GVW (gross vehicle weight) the plate lists both the "as built" capacity and the maximum possible capacity but that may require heavier springs and/or tires to get the maximum certified capacity. It does not list the GCW (Gross Combined Weight) like later trucks do (GCWR).

As far as trailer guides the only info I can did up prior to the '73 trucks are the RV brochure and the Silverbook RV spec section. The truck data book would surely have something as well but I don't have any conplete copies.
There might be something in the Longhorn literature but I cannot remeber for sure. The 12.5k number is about the highest I can remember seeing though. If anyone has a '73 Silverbook handy (mine isn't) the RV section lists C/30 towing as I remember due to the increased sale of recreational C/30s.

Final thing to remeber, a lot of states like here in CA limit towed trailers to 10k without a commercial license (or non comercial class A). But 5th wheel "rv" trailers can go to 15k with an endorsement as I have.

The '69 RV brochure only lists the C/10 and C/20 as well. The limis are lower than the '72 ratings which Disc brakes likely have a big part in.

Managed to dig out some Medium Duty brochures and the lowest to have a GCW is a C/50 and that runs 8k CS(six)to 21k CE(v8).

At this point though without the actual equipment level on the truck in question everything is a generalization.

I agree. I need to get my hands on the truck and get some more information.

I am interested to see where the specs come in at. I have a 2000 K2500 regular cab with a 7.4liter (with only 46,000 miles) that is not rated to tow something as heavy as my tractor. It is a great work truck, but I was really disappointed when I found out it was only rated to tow a maximum of 9,500 lbs! And that is both the conventional and 5th wheel maximum with a 3.73 rearend. Even if I had 4.10's, capacity goes to 10k for conventional, and 11,500 for 5th wheel... still not close to the 14k I need. Anywho...

Thanks again for all of the help from everyone! I did miss this board!
