Thanks that is great info. I believe I know one of you, ship in Kodiak? If so we have talked about some fuel issues we both have had and know each other from work!My sister and her husband have an 06 3500 srw truck/megacab and have had no trouble with a 9 foot lance camper. They do have 19. 5s on the truck and they use it exclusively in Alaska. It rides level and well even though the camper dry weight is 2500 or so.
