I second anywhere on the Kenai Peninsula, Girdwood, Portage Glacier, Whittier (as I never been there), Flattop Mountain, Arctic Valley, Knik Glacier Road, Willow Creek area, Nancy Lake, Deshka Landing, Hatcher Pass, the cove at the end of KGB Road (Knik Goose Bay) but watch out for a few of the summer homesteaders and partiers there depending the time of day or night, and everywhere else PA12DRVR mentioned as the Anchorage Area has so much to offer nearby.
The government campground in Hope can fill up pretty quick as the area of Hope itself is not generally crowded at all.
Areas mentioned on this post is within a relative two hour reach.
Pretty ironic as I still never taken my camper rig on the Kenai Peninsula to this day.
