I've done this drive many times starting in Southern Ontario, down around the lakes through the US and back up into Canada. (our best run was 2 of us did it in 36 hours door to door with the truck only stopped for just over an hour the entire time while getting fuel). After doing it for 10+ years I moved out here. Revvy is just down the road now.
Looks like border crossing stuff is already covered. Ownerships etc. We always had guys flying out and I would haul their sleds for them. In those cases I would carry their ownerships along with a signed letter that had contact info on it. Only ever had them ask for it once.
I found the more scenic drive to be across Montana and then up through Lethbridge Alberta or cross North of Spokane. Lots of mountain passes and crappy roads to get up to Revvy if you go this route. Definitely not the fastest.
The quickest and most direct is to cross in Portal, North Dakota, its a 24 hour border crossing. After you cross work your way North West up through Estevan and Weyburn towards Moose Jaw. This section has a lot of two lane highway with minimal passing zones so if you can do it at night you will hit less truck traffic. Once you get to Moose Jaw its pretty much a straight shot on the Trans Canada Highway all the way to Revvy.
For the most part fuel isn't too bad, it just costs more once you cross the border. All of the bigger cities throughout Saskatchewan and Alberta will have 24 hour diesel. Don't try to stretch it too far though, as there are some sections during the night that if you skip fuel in one city, you might not make it to the next big center.
Load up on gas, food, beer, whatever else you need before you get to the BC border. Everything is more expensive here than Alberta. BC = Bring Cash.
