I am ordering a Four Wheel Hawk flat bed camper. My current camper has a webasto diesel Airtop heater plumbed directly in to my main diesel tank (60 gallon main, 40 gallon gravity fed aux). I love it because I can disseaper to canada and alaska in the winter for 45-60 days and I never worry about propane I just fill up my truck at the fuel station and I'm on my way. While I know that the newer propane furnaces in the four wheel campers are pretty fuel efficient I still think in dead of winter trying to keep the camper warm that I'll only get 3-4 days on a 10lb propane tank and I just don't want to have to deal with it when I have an unlimited (basically) supply of diesel. I have a new in box Diesel Webasto Airtop that I want to throw in to the Hawk. My question would be if anyone has done this and specifically if there is a good place to route the diesel fuel line (QD?) since the camper will attach and detach from the flatbed when I am home and not traveling. I don't really want to run the line up the side of the camper or anything. Thanks
