I don't see a problem as long as you take extra tires on rims for both the truck and trailer.. and carry some Jerry cans of fuel.. The saying up there is never pass a fuel station as the next one might be dry.. If you have not yet done it Alaska and Yukon tourism have lots of info they will send to you..
When going up there do not miss the "Icefield Highway" between Banff and Jasper.. I host at some of the campgrounds along it in Banff
