Been road tripping to Alaska since 1969. I had a slow leak tire once about 1996, got it fixed in Whitehorse. Got a chipped windshield, but that was on the Oregon Coast.
Campground fees run about $35 per night, but there are pricier ones. Most electric is 30 amp. Some have on-site sewer, some have a central dump.
Look at the itinerary for a clue as to what they consider interesting and worthwhile. Also look in any copy of the Milepost, it does not matter how old it is, a Library discard from 5 years ago will do. Match them up to see if the tour is all that interesting to you.
There are very few road choices in western Canada and Alaska. The big decision is to go around Alaska clockwise or counterclockwise, take the Alaska Highway north and the Cassiar south, or the other way around.
It is a simple road trip on decent roads. The places you stop will have civil people who will be friendly and helpful. They all speak english, and all accept US dollars and credit cards.
If you like caravan travel, do it. If you are comfy on your own, skip the caravan and just take the trip.
We do it with a 40' 5th, and have used other RVs such as a FL50 carrying a car and towing a toy hauler. Easy trip, good roads, nice folks and good scenery.
