I got a 07 cclb on a lemon law trade in. The 04 was the same truck but with a 6.0 L gasser. I don't miss the old truck one bit. I put on the Flo Pro turbo back exhaust with a straight through muff. I love to hear the whistle. It goes in on the 29th for the trucks first Christmas present, a 4" tuff country lift so I can bolt on my 33's that I saved off of the other truck. I use this truck to tow a 26 ft toy hauler, scrap cars on a 16 foot car trailer, and of course, use it to haul firewood. I have no complaints. I want to do the intake mod and a mild programmer. Thanks for listening. I will update the avatar after it's transformation.
