Alaska by RV, solo or caravan . . . . opinions please

We are in the middle of our second trip from Florida to Alaska, 6000 miles and a month and a half, without a single reservation until we got here. Once we spent some time up here and decided what we wanted to do with our guests (daughter and grand-kids now and best friend next week), we made reservations for those time periods and activities. In addition to the MILEPOST and Church's book, get the "Allstays" app for your Ipad, and the Alaska Toursaver coupon book. It will save you lots of money.
