I almost bought a 07' 2500 crew cab short box several months ago when they had the 07' rebates. I held off because I couldn't find the color I wanted. Well, GM has the $3500 discount going right now and it got my attention. I made the drive out to James Wood GMC in Denton, TX and test drove a 3500 Crew cab 4x4 dually. I'm currently driving an 05' f350 crew cab long bed and I was really impressed with the ride of the dually! The allison and the Duramax are an awesome combination! The salesman and I went back inside and located the exact truck I wanted within 600 miles. He made the trade and it should be here in the next couple of days! It's a fully loaded-nav., sunroof, rear sliding window, rear entertainment, everything! In fact, it has a back up alarm (sure it will be disconnected)! I can't wait to get the truck. This will be my first personal dually to drive on a daily basis. I had a company truck that was a dually but didn't drive it that much. Hopefully it will become second nature! Add me to the dually club! Hats off to GM for a great truck. I've had three Powerstrokes over the past years and I'm making the change. Duramax BABY!
