Yeah, from my perspective, I never found the road system only access Alaska all that interesting thus the unexplained jump to fly out trips. That's where it all gets pretty incredible.
So your mileage may vary if you are intent on just the ANC area.
Also, bigger rigs are useful if you plan on hunting and meat hauling.
Another point,if you do get into fly out trips that involves a commercial flight to a off road system town then bush flight to river headwaters,etc. then it's almost somewhat a wash to just rent gear in the no Road Town, if available, when you get done with hassle, time and shipping costs.
Kind of a big reason I never moved to AK.... The difference in getting out to real Alaska type fly out trip costs are only a couple hundred in airfare different doing a trip from Denver vs Anchorage. All the expensive parts remain the same.
Anyway, typical buzz thread drift but maybe it helps in your decision.
And there is allot of cool stuff road system. Off the system is what the dreams are made of though.
Good luck.
