Congratulations, Boomer, on the Bolt!! It seems like a very practical EV, and it appears that CCS Combo charging will end up being good enough for getting around most of California if you're patient.
We are still appreciating the pre-owned Model S that we purchased last year. It is roomy enough to comfortably enable family camping trips, as evidenced by its now having 80K miles on the odometer (7K driven by us in 4 months of having possession of the car). Last week, we returned from a six day trip to Death Valley, where we stayed at Furnace Creek Campground (NPS) and did some great hikes in a number of locations around the Valley, including Mosaic Canyon where the narrow canyon's walls are composed of marble. Getting there and back required only the use of the Supercharger in Inyokern, CA, as well as the use of an RV outlet at the campground. Being able to set our air suspension to "very high" helped our comfort level when navigating short dirt roads up to trailheads and when crossing large puddles on the main roads left behind by flash flooding.
Unfortunately, our 2012 Tesla shut down last month in a Trader Joe's parking lot and it turns out that the main battery pack had a fault due to moisture intrusion. So we're currently driving around on a loaner pack that appears to be relatively new (it charged to 264 rated miles in Death Valley). Tesla will either repair or replace our pack within several weeks or so. While it's regrettable that our car has had issues, we feel great about Tesla's service and intend to purchase the Model 3 that we reserved for an older family member who wants autonomous driving functionality.
