Follow-Up:
Have a 2000 with 30,000miles by me. Have gone to alaska, from west to east coast twice and visited many states with nothing significant happening. With codes on dash the dealer has been the one most helpful. Like anything new there were some things that needed taken care of within the first 3-4 months. We have been detained for people look at the rig and take a tour given by my wife happily. We have gotten up to 23.10MPG.....which we enjoy.
