We just bought a new diesel motor home that required DEF, and we are planning a trip to Alaska next year. For those of you who have done the trip, did you have any problems finding DEF along the way?
My Chevy tow vehicle uses about one gallon of DEF per thousand miles, so with the 6 gallon tank I can run between south Florida and Fairbanks, then top off. I carry a gallon or two with me when on the road and use it before buying new as the DEF does have a shelf life.
