I have an 08 and love it. I am getting 13-14 mpg towing ~9000 lbs. The power and ride is unmatched by that of any other. On highway rides without towing I have seen 22 mpg. I LOVE my truck and will hold onto this one until the wheels fall off. The emissions crap is a bit of a PITA, but there are ways to bypass it if you are willing to spend the money and will give you better gas mileage. There was a recall on the new ones, problem with the ECM not allowing the truck to start, but if you buy one the warranties are all transferable, so they will fix it no problem.

The 05's are nice too, and like gr8shot said, the heating problem is a simple fix. If the price is right on the 05, I would scoop that one up, 30k miles is nothing for that motor. If you are going to be doing regular towing and have the money to drop on the 08 then I wouldn't hesitate to get it though. Oh hell, buy them both!!!!!
