I would like to get a newer one, but honestly I HATE the new body style and really like this one. I ran the VIN on dieselplace.com and it cam back with all the info on the vehicle. It has a WD hitch from the factory - rated at 15k #...and it also has the Allison 5 sp tranny.

You too, Brian. Thanks for all the help man - much appreciated.
Brian has been helping me try to pick a good tow vehicle. While he was here I borrowed a 2003 GMC Suburban 2500 with the 8.1L gas motor and Brian met me at our shop where I keep the boat. We hooked the boat up to the Burban and tried to tow it around the block. Sure, it did it, but it was a pig....not to mention it felt dangerous as hell. Lots of frame flext under braking over bumps and uneven road surface not to mention maintianing 60mph on a hot day with any hills would have been horrible. Anyone considering a similar Suburban should know that there is no way it's going to tow much more than 10k #.
Hence my choice of the dually....

Well how fast do you want to tow?
16-18k pounds going down the road is a lot different than an empty truck. It's SUPPOSED to feel different.
I think the body style is the same from '03 to '06 and you're best off with the later years in that range.
The hitch itself isn't weight disstributing (WD). There's two tow ratings based on whether or not you are using a WD setup. A WD setup is a contraption that compensates for too heavy tongue weight. The truck can "pull" the weight, but the factory hitch can't "carry" the weight. I'm sure Brian has told you more than once you need to get one of these: http://cgi.ebay.com/Putnam-Class-V-H...QQcmdZViewItem

Interesting response. I am in the same boat and really want to get one of these duallies. However, the highest number I have heard with respect to non WD for a GMC 3500 is 7500 lbs and that limit is the truck and not the receiver. I would love to be proven wrong here. The Ford on the other hand states clearly 15000 lbs for a non WD hitch setup and in this case the hitch itself would be the limit.

And I don't want it on my boat trailer. Look what the limit is without a WD, the hitch can say whatever it wants, GM does not publish it to more than 7500lbs. With this set up (the WD hitch mounted to your boat trailer), the new GMC publish the limit to 13.000lbs.

This is a weight distribution hitch:

The only auto you can get with 6.6 is the allison. Only rear diff ration with the duramax is 3.73. Second gen engine had injectors outside valve cover, mutch better engine. You still can add power up features with minimal interference with emissions components. There towing specs are straight from GM.

Hey guys. Interesting conversation. The LLY engine came with either a 6sp man or the Allison 5sp trans. The manual was discontinued in mid 06 model year. Assuming you have a 4x2, the trucks rated at 9500lbs with a standard hitch,12,000lbs with a weight dist hitch, and 16,400lbs with a 5th wheel. The LLY was rated at 300hp and 520 lb-ft of torque. These are based on 06 figures which are the oldest I can find.
If you have the vin# I can get complete specs and some past service history as well.
Just to clarify, the published ratings on your hitch have nothing to do with the tow ratings on your actual truck. The truck could be rated at higher or lower ratings than what the hitch is rated for.
