Take I-80 across and the obvious stops are Badlands, Black Hills, Devils Tower, Yellowstone/Tetons and up to Glacier. Cross into Canada Est of Glacier. There are many other places to visit along that route. Take your time, travel 200 miles or less a day. Stay multiple days in one spot. Fulltiming is a whole new game.
I'm still not convinced Canada will be open next year. Lot's of people thought the border would be open earlier this year, they grudgingly opened it on the 9th but with all sorts of restrictions. I have not heard a report from anyone crossing it yet.
