Anyway, so far what I am seeing here is that as long as I am at or under 22,000lbs GCVR with a max 3500lbs pin weight, I am within spec and technically legal. I guess a trip to the scales to tell me my "regular" truck weight is next so I can see what I have left over for the trailer out of the 22k total.
Be sure and get separate front and rear axle weights. A gross weight doesn't tell you much....if your over axle/tire load limits.
Sometime in the mid '00 GM shot themselves in the foot with the DRW truck. They actually lower RAWR down to 8200-8400 lb range by using lower rated rear spring packs for a softer ride. They admitted the mistake and upgraded the whole truck in the late '00s and went with a 9375 rawr with the same AAM 11.5" rear axle. AAM give the axle a 10xxx lb rating...one tough axle.
Upgrade the rear spring packs would fix that issue.
GM did have overheating issues with the Dmax LLY (??) engine . Check out some of the GM diesel websites for input on these trucks and what the fix was.....or any issue you might think of.
My sticker says 8550lbs GAWR. And the truck rides quite hard at proper tire pressure, interesting. Given that the actual axle is up to the task, would the addition of Timbrens or airbags serve as the equivalent of a spring upgrade?
3500 is the mix pin weight according to the manual, if GVWR of trailer is 16,700, that would put pin weight in the mid 3000lbs range using a 20% estimate. Is there a way to measure pin weight directly? Jayco quotes 2820, which sounds low.
