I thought the wait was long enough ,exactly 12 weeks. The shipping Co. decided to christen my truck with a damaged bumper and missing front hub cap. This kind of bothered me so I thought I would vent to those who have experienced similar misfortunes. On a positive note, No vibration and 15. 6 mpg without trying. Looks like I will have to get use to the extra gear as I am coming from a 5spd Hemi. I do love the wonderful smells and sound my new truck makes. Thank you to all for keeping me entertained with your thoughtful posts and replys. I am glad to be a member and look forward to sharing any info. that might be helpful. As my signature says the fridge is always full so if my way stop in and enjoy a cold one while we listen to the sound of music... Cummins style.
