William,
I haven't talked to Rog in a few days, but I think he's out looking for a quality Bull Moose with Norm. They have an area that they haven't been to in a while. If he's on the Yukon, then they took a jet boat up river.
The roads north of Fairbanks turn into dirt/gravel at the Yukon. The problem is not so much the road condition, it's the lack of service stations. You can get truck and tire repairs done at the Yukon crossing or Coldfoot. After that it's, slim pickins until Deadhorse. So, we take two ready to use spares and heavy duty tire plug kits. Other than that, just do a normal vehicle check like you're going on a long road trip. Of course I'm talking about summer and fall trips. In the winter we pack small 2 stroke generators to get our trucks thawed out so they'll crank. As far as survival gear, you should have that with you anyway if you've been out on a hunting trip. I love hunting up there. I double lunged a 38 inch Bull Moose last year on the North Slope with my bow. I had nobody with me except my wife... it was her first field dressing experience. Believe it or not she helped me alot and actually liked the whole trip.
The lay of the land has plenty mountain passes to get through. The roads follow river valleys as much as possible, but if your travels take you over a mountain range then you're gonna gain some altitude. Antigun Pass is the big one, but Gobbler Knob and the Finger Lakes area around the Coldfoot and Wiseman area are no joke sometimes.
By the way, I'm from Dallas, Texas. I've been in the Army for 20 years and last 4 have been here in Alaska. Aren't you from Texas too?
Take care.
