Yes you will be overweight I had a 2004 LB7 (basically the same as the 2005 LLY specs) 3500 Dually and the max as I remember was 14.5K and it did O.K. but struggled going up the bigger hills and overheated some so went and traded for a 2007 LBZ Dually and they the are rated for 16.5K and have more power and the 6 speed Allison Also do not forget LLY's had a Overheating problem because of a restricted turbo mouthpiece which can be solved pretty easy but anyway yes you can do it but you will be overloaded do yourself a favor and a least step up to a 2006-2007 LBZ Dually they are much better choice for what you are looking at
Interesting, my manual states my trailer limit is 16,500lbs. I also have the Alison trans.
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.
Whether or not I like how quickly it pulls is another topic, but it sounds like I would be ok, but with no reserve.
