We did the trip in three different travel trailers over the years, and just got back in September from our last trip, this time with a Class A. The trailers all did pretty well. Bent an axle on two trips, but one was clearly from a washtub sized hole on the turnpike in Ohio. Other issues were attributable to a low end trailer(early 2000s Fleetwood) that was not up to the task, including a fresh water tank the broke free and fell off the frame, and a spare tire carrier that cracked, and needed to be repaired in a little village in the Yukon. IMHO, the biggest prep. to do to a trailer for that trip is to protect the front wall from the gravel spray from the tow vehicle tires. On both of our aluminum sided rigs I removed the lower half of the siding and replaced it with heavy gauge aluminum diamond plate. Good luck with your next trip. I think a smaller trailer and truck are a great combo. for AK. It's nice to spend a few days out exploring, while the trailer remains parked in one spot.
