Check out Arctic Offroad. They are a 4x4 club based here in Fairbanks Alaksa.

There are several trails through out Alaska, but 2 of my favorate are:
1. Boulder Creek Trail - recently featured in Petersons 4Wheel & Offroad
2. Stampede Trail - Featured in the Book / Movie Into the Wild. I have yet to make it all the way back the the bus in my liberty, but it is a fun trail none the least.
Other Points of Intrest:
If it is open, the Denali Highway is always a beautiful drive. On a clear day you can see McKinley from just about every where. It's a rough road, but passable with a standard RV.
Copper Valley & Kennikot Copper mine.
Just a couple of suggestions...
