We use a combination of paper and electronic for planning. I keep an Excel spreadsheet for the distances for the day. I usually plan to the halfway point before we leave and then plan the return trip. I keep a blog in which I have pictures and descriptions of campgrounds and sites. I also print out campground directions if they don't agree with Google maps or my GPS or if the campground says don't follow the GPS on their website. I also have a map book that I use as a double check for the GPS and to see what is in the area. Hope this helps.
