I do a lot of flying around the Anchorage area. Alaska is a very big place. There are some neat places to go in an airplane though. There's a lot of remote strips, most of which are probably not suitable for an RV. But there's some good ones too.
If you get the Alaska supplement, there are some popular flying destinations in the back with information like CTAFs, and common, safe routes to fly. Especially around Denali National Park. Even an RV might have a hard time getting above some of the terrain out there. I'd also recommend you bring a PLB with you. I never fly without it. You can get 20 miles outside of Anchorage over terrain where no human has ever set foot.
Around Anchorage, my favorite destination is probably the Knik Glacier. It's a 20 minute flight from Anchorage in the C-182. I flew out there earlier today, matter of fact. There's a 600 foot dirt landing strip out there. I have never landed there. I usually see super cubs out there. It's NE of Anchorage and very obvious on a sectional. Every time I'm out there, I see lots of wildlife. Especially moose. We counted close to 30 today. I see bears, goats and sheep too.
I also like to fly down to Seward. It's a beautiful flight through the mountains. It's on the Kenai Peninsula. The Kenai is beautiful. I could spend days out there flying around and exploring. Homer is another great place to visit on the Kenai Peninsula. The airport is right in town. I'm pretty sure a couple of the hotels on the Homer Spit will come and pick you up. Homer is beautiful. From there, you can fly to Seldovia. They have an 1,800 foot long gravel strip. It's a fly in only type of town. There's some good fishing that you can do there within walking distance of the airport.
Talkeetna is a good place to visit. The flight up from Anchorage is pretty flat, but on a clear day, you'll be staring Mt. McKinley in the face. From there, fly up to the Ruth Glacier on the south side of the mountain. Fly north up the glacier into the Sheldon Amphitheater. It is absolutely incredible. I wouldn't go if the winds are blowing more than 15 knots aloft. But the winds are usually pretty light here in Alaska. There's also a LOT of traffic around the Ruth Glacier. From Talkeetna, you can take a flight seeing tour that actually lands on the glacier and you can get out and walk around. If you're in Talkeetna, you can walk to town in about 10 minutes from the airport. I fly up with the family occasionally and we eat at the West Rib restaurant. It's good food and the prices are decent for Alaska.
Another fun place to visit is the Skwentna Roadhouse. PASW on the Anchorage sectional. It's about 30 to 40 miles WSW of Talkeetna. It's a fly in only type place but they have a very nice 3,400 foot gravel runway. You can walk to the roadhouse from the parking area. Or, you can call the roadhouse on 122.9 and the lady that runs the place will come out and pick you up for the scariest ride you'll have on the whole trip. I flew up with my kids last winter and she picked us up on a snow mobile (snow machines in Alaska) that was towing a black plastic tub with some wood to sit on. It's a wild ride. The Skwentna road house isn't too fancy, but the location is awesome. You can fish there too and they have guided tours in the summer. If you're not from Alaska, just pay a guide to take you if you want to fish. Fishing here is very difficult for a whole lot of reasons. But the Skwentna Roadhouse is like a bed and breakfast and you can spend the night. She'll feed you too! Very nice people out there. The runway is gravel but will not be a problem for an RV.

Valdez is another great spot to fly into. They have a nice, big paved runway. It's 100 miles east of Anchorage as an RV flies. I can make it there in less than an hour in the 182. It takes me 6+ hours in the car. It is a very beautiful place and the flight out there from Anchorage is incredible. You want to pick a clear day. The terrain out there is very unforgiving, but absolutely beautiful. There are mountains that drop off steeply into Prince William Sound. If you're low enough, you'll see whales in the summer. There are glaciers everywhere.
The north slope would be fun to fly to. It's pretty far and remote out there. I'd avoid the small villages here in Alaska. If you wanted to go to Nome, that's about 450 miles from Anchorage. The flying through the Denali range is beautiful. You could stop in McGrath for gas. McGrath sucks. So does Nome. They're pretty dumpy places, but some people want to go. Kodiak is a neat place to visit. The weather can be sketchy out there. It gets worse as you head out in the Aleutian Islands. There's a couple of volcanoes erupting out there right now. It's so remote, and the weather so terrible, that people don't usually get pictures of them.
There's tons of great places to fly into. I'd say that most of the good stuff is in south central Alaska, and the Denali range in central Alaska. But believe me, this is probably the most dangerous place to fly in all of North America. Pilots die here all the time. I am extremely conservative when I go fly. It is very remote. If you're not flying through mountains, then you're flying over swamp land. Having a PLB and some good survival gear is a must up here. You may survive a landing out in the wilderness, but you can die of exposure in one night. Even in the summer. I fly prepared to spend a few days out in the wilderness. Even if you have a PLB, it can be a few days before rescue can get to you.
Get familiar with the Alaska Aviation Weather Unit website.
http://aawu.arh.noaa.gov/ It has lots of good info. Especially the weather cams which are all over the state. In my opinion, June and July are the best times to come up here for anything. August is nice, but tends to be wetter in my experience. I've lived here four and a half years. September starts getting cooler and is still rainy and October pretty much totally sucks. The suck continues through mid May or so. It's getting pretty nice here now. I had about 3" of snow yesterday at my house in Anchorage. Today was beautiful though. Supposed to be in the upper 50s by the end of the week! Come on up right now.
