Okay here's the route: https://www.rvparky.com/trip/4547933076979712
For most one night stops we will be stopping in parking lots or truck stops. Basically we will drive until we are done and find a place to stay. RV can hold 100 gallons of fuel so we will not have to stop but once a day for fuel. We will have a toad on a tow dolly up until Spokane. There we will drop it and just tow the dolly home. Assuming my husband doesn't find something he must have along the way.
We have a three-day buffer for this trip, which leaves us time for a break down or an interesting spur of the moment side trip.
I still need a place/park to stay in West Yellowstone. Recommendations?
