Just East of the CA/NV border right off the I-80W, a short spin from the 80E and adjacent to an Indian Reservation smoke shop, Gold Ranch Casino and RV park couldn't be much more conveniently located.
They have most of what a RV traveller wants and just about all a car traveller needs. There is a gas station with a travel center shop, a diner, casino with clean restrooms, a Jack-In-The-Box burger joint, lots of parking and an R.V hookup park around back.
If you are heading over the Sierras, you definitely want to consider getting gas here rather than paying a buck-fifty more up ahead. Also, this is the last gas till Truckee.
