Seward and back is easy in the summer. It’s too close for me in the winter. Did it once and Made it back to Anchorage with 6%. Denali is easy (in the summer) since there are tons of 50a RV hook ups at the park entrance to charge off. Fairbanks requires 2-3 hour stop at the Talkeetna junction or 49th state in Healy. Homer requires an overnight.On a full charge with a LR I think you could plan a fishing trip weekend from Anchorage to Seward or a one way trip to Denali State Park.
For an EV to be your only vehicle we desperately need superchargers at all the junctions: Tok, Glenallen, delta, talkeetna, Fairbanks. And the end of the roads: Seward, Homer, Valdez, Haines. After that Anchorage and soldotona. That would pretty much get us.
