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.
