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?
In Canada, any Canadian Tire (CT) store, or even Walmart, should carry it. I've seen gallon jugs of it on the shelf at CT stores in Port Alberni and Nanaimo, so I would suspect any of the stores should have it.
