The only concern that I've had about upgrading to a diesel RED or FRED, is WHERE to get diesel off the road. I guess you fuel up where the big trucks do while on the interstates. (I once witnessed a new DP owner trying to figure out how those diesel pumps worked in 'pairs' one on each side! Somebody might could explain that.) What about while driving around in the country? In the small towns? My Class C 32' gassergets along fairly well with the little cars in most regular gas stations, but if I were to go up a notch to a DP, I can see where I'd have to change the way I plan fuel stops. What's been ya'lls experiences with refueling out in the hinterlands?
