Ed ..Thanks for sharing your trip . My wife and I went to AK. in 2013 towing a 21 ft 2001 Trail Lite. Used sons Jeep Grand Cherokee with small V8.
from N.W. Wi. and back 8600 miles in 6 weeks. Bought a 2011 X23B last year and love it.
We are planning on going back in 2015. The Jeep made it but we are going to up size with a bigger V8 in a truck. We passed on the Dawson Chicken road but loaded up our rig on the Alaskan ferry at Haines AK. and got off in Prince Ruppert Canada. A great adventure inside our Ak. adventure.
My wife filled up a 16 g sd card taking pictures.
The frost heaves on the roads in the Yukon were memoriable.
