But there are certainly routes within "covered" states that are not on the main interstates that therefore do not have Superchargers. And for a round trip, you could certainly go 100 miles out and 100 miles back to make a 200 mile trip that is not covered.Jeeez where is this place you are going. I thought North Dakota is the only state with no superchargers.
I concur with a couple of folks, though--if you're on a remote route, there are usually campgrounds or RV parsk or something that would be available for charging if needed.
