When you are planning a new trip/route, you will have the option to start with a "blank" trip or a "recommended" trip.
Blank - this is a trip that will get you from your chosen point A to point B with no suggested campgrounds provided so you can choose all your stops along the way and build the trip from scratch.
Recommended - this is a trip that is built for you based on the specific requirements you have added (drive time, cost preferences, etc). We add recommended campgrounds to the trip at intervals that suit your requirements so that you have a base to start with when planning your route.
You still have the option to swap or remove any pre-populated items, but the idea of the recommended feature is that you have a baseline trip suggestion. This option is nice if you've never used Road Trip Maps before, if you are unfamiliar with an area where you are traveling or are simply new to camping.
