Loved reading this thread and stoked for someone to have a proper adventure! We just got back (month or so ago) from a 6,600 mile trip from East Coast to NW Montana and back. Great surprise of the drive was Western North Dakota. Roosevelt's old hunting grounds were AMAZING.
Few extra thoughts:
- 5 gallons of emergency fuel in a jerry can made a few longer stretches a lot less stressful - If I was towing, I'd double it. Didnt need it, but came awfully close
- Home2Suites was a great option when we wanted to stack miles through the night and skip a camp - dog friendly, cheap and easy - there was always one within a few hours and no more than 10 minutes off route - never planned ahead and it just worked
- People were exceptionally nice everywhere but mask use changes drastically every 50 miles. Carry one and err on the side of mask - made us a lot of friends and no skin off our backs
- We missed dinner almost every evening while driving - constantly waiting for the next spot or assuming my nav was incorrect

. That made a jetboil and some good camping food a great alternative with way better scenery
- Have a friend with a drone? Mavic's are crazy easy to shoot and make some of the breaks in driving a lot of fun... your yeti will keep it all charged up. For a young family, you can have it hover and do your thing so everyone is in the shot.
Enjoy! We're already planning our next one
