That's a long trip for your first outing!
I bought our present rig in Cornwall, 100 km from Montreal, and drove it home to Kamloops.
I would suggest that you buy a tool kit, volt/ohm/amp meter and maybe some other repair materials from Canadian Tire. That's what I did. Returned when I got home because I didn't need them.
Take the Southern Trans Canada Hwy. because it's more populated in case you need parts or ?
Have a good trip.
