I have lived in Alaska for 30 years and never had the need to caravan with any group anywhere in the far north (even in the Northwest Territories in my opinion is one of the most remote areas by road such as Fort Simpson, Yellowknife, etc.), the far north is not like going thru the Darien Forest in Panama or going remote in South America or some other area even more exotic or foreign.
I would travel upon the best way you feel more comfortable with, as we all own our RV's and live for our travels in order to roam around free.
Why would any of us want to caravan around in our own RV's is the real question, and if you have the right answers in mind then weigh in the factors....
Don't get me wrong, it's always nice once in a while to travel with a larger group such as a motorcycle club or organization together and all that, however if you feel you are an independent RV traveler like most of us, as they say -fugeddaboudett and just go explore on your own pace.
You will more than likely run into the common obstacles of the factors that Sue had posted such as road conditions and natural occurances that could throw off a scheduled plan or delay of a day or two but that is part of travelling the far north.
Did you know that they actually have Walmarts & McDonalds there? They really do.
Since this was mentioned, I had the McDonald's question thrown in my face a half dozen times once someone finds out I am from Alaska...
The last time when asked was back in 2001 when I arrived at McCarran Airport in Las Vegas, I walk by Carrot Top and said hi which turned out to be a 5 minute conversation while we both were waiting for our luggage, as he asks me where I am from and if they have a McDonalds in Alaska....I tell him well sure, we got like 12 McDumb----'s (of them) in the whole state.
He laughed hard at that one, and all the other Alaska jokes I was rolling at him one after the other.
