First Trip through Canada & into Alaska - Many Questions!

Did this trip last summer, GMC 1500 pulling a 27' Catalina. Roads are good with plenty of hills in northern BC and Yukon but just take it easy and should be no issues. Book the busier camp areas early before your trip ie Dawson Creek, lots of caravans take the campgrounds. Ones I didn't pre book I arrived at a decent time around 4pm. Cell coverage is very sparse so make sure your units are well maintained. Gas I never had an issue with except on the Yellowhead Hwy in Saskatchewan
