good info, thanks.
do you have the list for the diesels? I would like to compare it.
So for years most if not all have gone with the 20-25% pin rating, now its 15%??? All the manufactures that I have been in touch with still go with20-25% Even GM when I got the truck new. In fact the sent me this link. Look at page 5, SW truck pulling a cimarron horse trailer (18k+ then add in LQ) with tongue weight of 5k plus( I called the people at cimarron for the info). That's way past the specs!!!

This is for my truck to help you get started, read page 40
Tongue or kingpin weight cannot cause the vehicle to exceed the GVWR (Gross Vehicle Weight Rating) or the RGAWR (Rear Gross Axle Weight Rating).
My numbers for the trailer are under the above specs.
trailer- 11040 with a pin of 3500 = 30% I took out all of my stuff and it went down to 10500 (3150 pin). The trailer is rated for 14k loaded.
Everything I could find stated that the duallys are built with the same parts, not options. So a high country with all the same rpo codes for both gas/diesel are the same truck till you add a bigger/smaller engine. So the chassis is the same till the engine goes in. If this is the case and it is according to all sources then its about 6-8 hundred lbs different. Going by the above list how is it that 15% is the rule when I can add up to 30% and still fit in the ratings, just not the pin. Wait I still have more payload that can be added, just don't call it pin weight??????? Did I make that somewhat clear what I wanted to say? This topic has made me crazy, year to year the trucks get bigger(hp/tq) and seem to be less on towing.
The pics in the manual is what really made a mess of my homework when looking into my trailer. That trailer had over 2k more in pin weight(the one in the pic, p5) as mine and is being towed by a SW hd.
I want to add, I don't use my truck for a living. I also do not claim to know all that some of you reading do. I just do fact checking. Please add to this post in a positive way, thanks for the reply Another JR
