The new diesel is "wow"

Brian, 10/16/2007
2008 GMC Sierra 3500HD Work Truck 2dr Regular Cab 4WD LB DRW (6.0L 8cyl 6A)
This non dually 3500 with the new diesel is a blast and very man like. I just purchased a 2006 3500 dump for my construction business. I love the fuel economy and the way it pulls my big trailers I didn't care for the new body style so I found a new 06. I added a pickup this month and all they had were 07 & 08. I bought the 08. Holy cow is the power different. This truck is sharp and … can pull a trailer. It gets worked on job sites and I pile the mile on. Good fuel economy and pretty comfortable for a 3500. I will buy more as I update my fleet from Ford to GMC.
