.I live in Alaska, and have driven the Alaska Highway many times, including twice this summer. I can tell you that range for an EV would certainly be a concern for that trip -- especially in northern BC and the Yukon. I had some range anxiety in a few stretches with a HD ICE truck pulling a heavy load. But I'd expect that to be changing in the next few years. Plan the trip carefully, based on needed stops. If there's anything I can do to help with you plans, let me know.
I also am waiting on Silverado details to decide on how I can use one. I'd like to pull a larger camper, but will decide when I know more details. I have Silverado reservations in AK and GA, and will decide which to use when details are available.
