We seldom make reservations. The main reason is that because of how we travel (stop & see the sights) we really don't know where we'll be in the evening. Once we're ready to stop for the night, my wife will look in the travel guide and find something up the road. If she can't find anything we'll look for a place to spend the night. This could be a big box parking lot or off the road somewhere. This is quite normal due to the fact the 40% of the campgrounds do not call us back. We have adequate solar and batteries to get us through the night or even for a longer if necessary.
