We rented an RV for a week back in June of 2014. Our favorite campgrounds were in the Portage Valley, which is about midway between Anchorage and Seward. Black Bear and Williwaw are the names of the campgrounds. June is pretty early in the tourist season, so lots of open spots, we were able to camp right next to a cold mountain stream. Nice and quiet.
There is a gas station with an RV dump in Girdwood (on the way from Anchorage to Portage Valley / Seward), and there's a ski resort near there. There's also a touristy gold panning operation and some good hikes, including a hike that includes a human-powered tram across a gorge. Here's me and my son using it:

Pretty cool.
