We've done a number of Alaska trips, never with the Ollie. Flew up 20 years ago and rented a small class c. Delivered several rentals from Indiana to Alaska over the years.
It's a very long trip. Our favorite part of the trip had always been northern bc, and the Yukon. But, you can fly in and rent there, too.
Not Ollie purists. We've rented campers on several continents, when expedient. Love my Ollie, but not shipping it to Europe, Australia, or Iceland. Rentals often make so much sense.
Glad you had fun. May is a bit chiller, bit a great time to visit Alaska. Fewer bugs. Fewer tourists. Fewer fires.
Good on you for great timing.
