Ok here is my dilemma I need another dump truck and I would like to buy one before 12/31 so I can get the tax break this year in 09. I have the opportunity to buy a GMC 4500 with the 8.1 liter gas engine 2wd with complete dump bed on it. The price will be around 40K and I have about 2300 in GMC rebates I can use from my credit card. I also heard GM is cutting this mid size truck out of thier fleet. I guess sales are bad. I really like this truck and always have, I just dont know how well it will work or last. I would assume it would last alot longer then your standard 1 ton. or I can buy another 1 ton pretty much the same truck I have now just newer. An 2009 GMC 3500 Sierra with a 6.0 liter, 2WD with complete dump bed for about 26,500 plus taxes. Minus my credit card bonus. So basically I would spend roughly an extra 10K just for the truck. I just want to know how well the 4500s hold up, work, and perform. Like I said I have a 1 ton an 05 Sierra, and its been a good truck. Not many problems, I just run into weight issues, and towing my bobcat. I have a 7 ton trailer that I just make under the cdl limit by like 400lbs. If I get the 4500 Ill need probably a class B. Anyone out there own a 4500 and can give me there personal opionion on them that would be great.
