I think you meant 287 from Virginia City to Dillon, MT via 41, then 278 to Bannack, then 278 to Wisdom via 43, then to the Idaho-Montana border to 93. We've driven those routes with our FW. All two-lane good blacktop highway until you turn off 278 to go to Bannack, and it's a good dirt road, at least when we were there. We stayed at one of the two campgrounds in Bannack - Vigilante and Road Agent. We stayed at Vigilante at the recommendation of the state park ranger because the sites are bigger. With your Class C, you would fit in either one. If you go to Campendium and search for Bannack State Park, you will see our review listed under "Hidden Gem!" by ReneeG. We'd love to go back again, late season as we did. Beautiful area and a lot to see.
