While we have never taken our RV up, we have tent camped in Valdez. I believe there are two private campgrounds in the town of Valdez. There are also two city of Valdez campgrounds near by. The two private ones offer full service ($30 -$45 a night) The two city owned campgrounds
($ 10 - $12 a night) are non-electric. The one city owned (Allison Point
) is across the bay from the Valdez and offers bay front sites (parking spots). If you want to doing fishing, this is the spot....There is a 500 gallon fresh water tank to fill jugs for cooking and a modern outhouse. The views are beautiful....If you are here in Aug. you will find huge blueberries behind the parking lot, up the hillside. Watch for bears.....You will also find salmon-berries here. Salmon-berries are like yellow or orange colored rasberries. They are the size of your thumb.
While in Fairbanks the new Visitor Center has good parking for RV's. The Riverboat Discovery
boat tour is a must do, but it is pricey. Chena Hot Springs is located about 60 miles northeast of Fairbanks. It is a nice road up to the hot springs. There are 3 state parks along the way to camp, but they offer no electric service.
Traveling south towards Tok and Valdez there are many pull-offs. The road is generally nice except for perma-frost / frost heaves. This means generally the road is flat, but there will be little humps in some sections of the road. Traveling in a car, you can stay at 60 MPH, but in a RV you would want to slow down a bit.
Here are some pictures from Denali
We have family in North Pole, so we have been up 5-6 times the last 20 years..
