We run 93 up into Idaho off I80. Can't say we have ever stopped for much except fuel. We kind of like the drive as it is a break from Interstate travel.
When we passed through Ely on 50, we stayed at the KOA there and shared it with a couple of other ASs. Nice folks. Good overnight stop. And we enjoyed 50 to that point, much more that the trip over to Colorado where it gets fun again. But that does not help you much with your trip plan. Interested to hear how it goes for you.
If you roll to or from Las Vegas, the KOA at Sam's Town was a surprise. It is a gravel parking lot, but a nice one. The side story is that our stay over night was the first night we have spent in Las Vegas. Always punted on the rule to stay multiple nights and kept on traveling. So other places may be better, but we would stay there again.
Enjoy your adventure. Seeing Nevada from a different direction is advised. Fuel up when the opportunity presents itself. Pack your water and enjoy the trip. Looks like there are a couple of rest areas along the route.
