UPDATE: Thank you for all of the suggestions. I was out voted this weekend and we have decided to fly to Montana and then rent a car. My wife is not comfortable driving an RV and I would be naive to think I could do it all myself.
Now if Montana would open. I was shocked to see they require a 2 week quarantine for visitors. That is slated to end today so I will be checking to see if it is extended or lifted. We still have a couple of months so hopefully things will be somewhat normal by then.
