As a follow up for anyone else making the trip, I left twin at 93% battery, arrived at jackpot at 67%, stayed one night and then made it back to the twin supercharger with 47%.
Yeah shouldn't be an issue at all. And you could probably find a 110V outlet to plug into somewhere if you were staying in Jackpot for multiple days (but why on earth would you? lol). As you found out, Jackpot is not really a town at all. It's just a few casinos and a couple gas stations.
It's only 50 miles away--not even a question. But if you do need charging, there are options just slightly better than a wall outlet. The RV sites next to one of the casinos do have TT-30 outlets for people's camping trailers. Those are 120V 30A outlets. But they don't seem to have the bigger 14-50 outlet sites.
