My '05 2500HD Duramax tows my 292 Fastech great! I love this truck. Lots of room, good ride, decent mpg, and tightest turning radius of any crew cab truck out there.

I sell GMC trucks! I took on trade a couple of Titan on GMC's. Mostly pulling 5th whells, customer were generally not so happy with handling and left to right movement when loaded. Engines were good but often not quit enough torque... Now, do what you think is better!

Don't buy a new Chevy or GMC. They are releasing the new model later this year, so you will loose a ton of value if you buy now.
If you do want the gm, make sure its a used model.. so you don't get killed in the depreciation.

New models are supposed to be 08 model year ans should be out to market mid summer 2007.

That's not what they said at the Detroit Auto show where the New Tahoe and Yukon are being displayed and are now showing up in dealer showrooms. The new pickups will be released later this year...'07.
I would wait if I were looking to buy new as they finally addressed the big problem with those trucks...the crappy interior!

maybe you are right for the US... Hope it changes for sooner in canada!

I know yukon and tahoe are for this summer in canada too.

Go with the duramax if you can. I have a 2004.5 2500HD crew cab with the lly moter and just love it. I've put an aftermarket exhaust, cold air box, and the edge juice module and those mods made it a blast to drive and improved my milage when I keep my foot out of the throttle. It also pulls my 10,000 lbs work trailer with no effort.

Did the samething to pull 12,000lb boat and trailer.it's fun to drive aslong as you don't like to see the black smoke coming out of the exhaust when you nail it.

are you sure you are talking about your truck
