Good, but not great

2005 GMC Sierra 2500HD 4dr Crew Cab SLE 4WD LB (6.0L 8cyl 4A)


This diesel was an upgrade from a gas Dodge RAM1500. Pulling a 7,000lb trailer now seems effortless. Turbocharger takes a long time to engage and gas mileage wasn't as good as I'd expected for a diesel- about 12.5 pulling trailer which is disappointing since over 20 without. Just had 3 injectors replaced under 100K Duramax warranty which I believe was a known problem in all GM diesels from 2002-2006. No recall, of course! No significant change in power or mileage with the new injectors. I hate that GM always adds a $95+ "diagnostic fee" for the computer hookup with any service. Also- computer's trip timer hasn't worked since purchase and the stereo speaker sound is absolutely awful.

Best Features

Nice ride, quiet for a diesel, and handles way more than 3/4 ton payloads with ease. The "trailer mode" works great on hills saving lots of wear on the brakes.

Worst Features

Make a step bar standard- these things are high off ground. Also bigger and better grade tires. I've been through 3 sets now at 66K miles.
