Hopefully, this post will be moved to the Alaska forum.
First, you might consider taking the Alaskan Ferry from Bellington, WA through the Inside Passage for a real treat of areas you can't drive to. It's about a 4-day trip. We left our motorhome for a month in an RV park in their storage area.
Many have rented and the best way is out of Anchorage. We did the ferry and rented from Great Alaskan Holidays are were very pleased. We got off in Skagway and rented for 2 weeks from a small operator - expensive but that was the only available. Then we had friends fly in and we met them in Anchorage, turned in our rental and re-rented for 2 weeks from Great Alaskan Holidays - much cheaper. We then toured with our friends for 2 weeks. We flew back to Seattle.
The rental was fun but very expensive. Plus, we felt rushed for the time period.
Later we drove our motorhome up leaving in May and returning in Sept. It was the best trip ever. We had our own stuff. We were able to take our time and explore Canada and the Yukon, also...something you can't do in a 2-week rental period.
Our 40' motorhome fit everywhere we wanted to go. There are so many wonderful boondocking spots in awesome spots overlooking rivers, lakes and mountains. We also used Provencial parks in Canada and the Yukon and some national forest campgrounds in Alaska along with state recreation areas. We stayed in Denali 10 nights at both Teklanika and Riley Creek campgrounds.
Bottom line, there is so much more to see than Alaska. The drive up and returning were great and the animals were plentiful.
We bought new tires before the trip. We were confident in our prior maintenance of the vehicles. That's the only protection we did and had absolutely no issues on the motorhome or Jeep.
Renting is o.k. but driving the distance is better!
