In June, we will be travelling from CA (the US one) to Alaska and back with a diesel truck and travel trailer. I know fuel will be more expensive in Canada based on higher taxes. I wonder if the same is true for DEF? Also, I wonder how common it is to find pumps with DEF at truck stops. My guess is that I will be better to fill the DEF tank before I head north and perhaps top up in Alaska, but any advice will be welcome.
