jaycocreek, Lolo pass doesn’t even count as a pass except it gets snow with a max speed limit of 45. Nice try though. Fwiw, my drw gets great mpg through there as well, but dw hates that road. :D
Anyway, I think the he’s in Canada is a red herring no matter how many times you repeat it.
Sounds like you don’t like diesels, but the fact remains that they are extremely popular for a reason. And ... that reason isn’t because all of the owners have fivers. You might want to think abou this for a minute to see if you can come up with why. :D
Back to the OP question though, DRW is preferred to give more flexibiliy with what OP carries.
