I was in Death Valley last weekend. Drove there from SF with Model Y, ended up renting an ICE car to explore the park, especially since we were staying 1.5 hours from the center of the park.
I saw several Teslas around the park, and I think it's doable if you only want to visit say 1 or 2 locations, but without a Supercharger in the middle of the park, you will be limited and won't have the flexibility to see everything.
The resort in the middle of the park has 4 J1772 chargers, which would help if you were staying in the park overnight, but we were simply doing day trips.
