Towing ? thru WY, MT, & Canada Hyw 3 to Vancouver
I am planning a trip from Arizona thru Grand Teton, Yellow Stone, Glacier National, into Alberta and take HYW 3 across to Vancouver and down the 101 into CA and back home. There will be some segments that I am not familiar with from WY-BC and I will not be able to make all of the trip myself as I need to fly home for parts of it to work, these areas my wife and kids will be making on their own. We are used to towing in the mountains up to 8-9,000ft, are there any extra surprises or cautions to be taken in the areas mentioned above.
We will be driving a 2011 F250 towing a 13,000lb trailer, we will also bring the side by side and be looking for some good spots to ride it as well.
