We stayed here in a 40' 5th wheel. We parked in the west row along the trees. This was a good spot, but the sun goes behing the trees about 5 in summer, if you are looking for solar charging. We noted that the parking rules are pretty loose as to where you stay. If the RV spots are full, we saw several just pick a spot in the regular lot. If you keep a clean area you may be able to stay more than 5 days, we did. The water spigot is on the south side of lot near the turn in. The trash cans can get full quick. The pay stand is on the north side of lot near the first entrance to Pioneer Park, by the small shack. No out of state checks. You can also pay in the office inside the park during business hours.
It can be noisy at times because of the close intersection. Some generators are LOUD and one guy ran his about 12 hours a day. I would think an extra battery would be cheaper than all that fuel.
It is a very busy place with the park and Alaska Bake activity. Lots of cars and the lot gets pretty full with that sometimes.
Free dump and water fill at the Sourdough gas station located at Van Horn and Lathrop streets just a few miles south, with easy rig access.
We would stay again if we ever go back to Fairbanks.
