I, too, would keep the Airstream if it is working for you. After the trip to Alaska, then I would see if your needs might be different and then revisit the idea for a change.
We were thinking of taking our coach to Alaska this year but opted for an Alaskan cruise instead. I just didn't want to damage the paint/windshield and there is so much beauty in Alaska from a ship that you could not get to by road.
The glaciers are breathtaking along with the misty fiords. The two week cruise started in Seward, AK, and ended in Vancouver, BC. The temps were generally in 50's and 60's... perfect for July! I had forgotten that the sun in Anchorage only goes to dusk, it's daylight for 24 hrs. at that time of year.
In 1997, we took a motorcoach tour from Vancouver to Anchorage traveling through the Yukon that stopped every evening at hotels. This trip also included a train trip then ended with a one week cruise down the inside passage back to Vancouver, BC. (trains, planes and automobiles).
Safe travels,
MM.
