Hi to all members. I found this site while searching for information on my next truck. I drive a 2003 Yukon XL, and put about 25,500 miles a year on it, with about 5,000 of it pulling a 4,500 snowmobile trailer. I am thinking of buying a Sierra 2500 with the LBZ diesel with the Allison 6 speed. I am looking for an idea of milage both with and without the trailer. I wish GMC would put a diesel in the Yukon XL, but I don't see any hints of that happening in the near future. Thanks in advance for you input.
