I'm at a crossroads. I've been thinking about buying a 2009 2500HD with the 6.6L Duramax diesel. The dealer I'm working with has a 2009 2500HD Crew Cab 6.6L SLE that stickers for $50.1K. With all rebates and incentives I can buy the truck for $38.9K. I have a 2007 Chevy Avalanche (currently 53K miles) that I purchased used last year for 26K. The real issue I have with the Avalanche is the lack of power with the 5.3L when pulling my camper. So, I left the dealer this past Saturday with them giving me 24K on a trade-in for the Avalanche and the price of the 09 for $38.9K. I really wanted 25K for my trade-in because I really wasn't 100% convinced about buying the 09 GMC 2500HD. Well this morning the dealer called and met my offer of 25K trade-in and $38.9K for the 09 GMC 2500HD. The Avalanche is the LTZ with EVERY option available from GM and the 09 GMC has basic options. What do you think? Never owned a diesel before but my dad owns a trucking company that has 14 diesel trucks. For the most part, a 2500 is way over kill for my needs but when I do need it I'll have all the power I need. Do I put up with the 5.3L or love life with the 6.6L Duramax?
