Probably way too much truck for that. A C-60 with adequate wheelbase should suffice, since your camper and snow machines would probably weigh much less than the crane and the flatbed (which presumably is designed to carry a heavy load also).
Also, even though heavy all wheel drive trucks are way cool, there really isn't much use for them. Are you really going to take it where you need all wheel drive? We hardly ever engage the front axle on our ex-military 6x6 trucks even for wildland firefighting - but use low range a lot. Then you have to consider recovery options for such a big truck!
When I was in Alaska in the late 1970s I found that there weren't really that many places where my K-20 was all that useful. Most of Alaska seemed to be either a somewhat developed road, or impossible bogs, inpenetrable forests, or glaciers. It wasn't like CO where there was a two track to the top of almost every mountain. A bunch of us
did go up and glean some firewood from a fairly recent power line right of way - that was a lot of fun following a bulldozer trail
Maybe it's different now or different where you are .....
