To the OP's Q's 1 - 3
- Would strongly suggest bringing the Jeep if that is do-able with other considerations: hanging a dirt bike off the back of a Jeep would be hard on it for the long drive up.
- Lots of places to fish on your anticipated route. Although interior AK is not as crowded for salmon as other places, it's also not as good: I'd suggest focusing on lakes and streams (trout, char, dolly varden, burbot, etc) except when you're in Los Anchorage or Kenai: there are several flyout options available from Anchorage (a few in Kenai as well), but there are multiple drive / boat options from Anchorage or the Kenai Peninsula generally. Depending on the time of year, I'd suggest dropping the coin and taking the time for a combo charter from Seward or Whittier. (Combo halibut, salmon, possibly rockfish). If you don't want to pay charter boat prices, there are several day trips for salmon and trout that are based in Wasilla / Willow / Talkeetna general areas.
- Not a campsite specifically, but if you're setup is up to it, drive the Denali Highway from Cantwell to Paxson or vice-versa. Spectacular scenery, but a bit of a rough road.
The haul road itself should be a scenic trip...although I've not taken it for decades. Got lucky on the long-ago last trip and left Fairbanks in what might pass for twilight....went North far enough / fast enough that it never got dark until I returned to Los Anchorage a month or so later. There's usually a period of 6- 8 weeks of no sunset up North, but it was interesting to be on the front end of that phenomenon.
