How do I add or change Campground Filters in the Trip Planner?

When using the Trip Planner and selecting a campground for each stop (by pressing the tent icon next to the stop name), you can select campground amenities that are important to you.   If you have already set your Campground Preferences (under User Profile >> Settings >> Preferences >>), these settings will be shown in your Campground Filters when using the Trip Planner (only the "Need to Haves" will appear in campground filters, not the "Like to Haves."   If you have not selected Campground Prefences under your User  Profile, you can set them in the Trip Planner.  However, filters set in Trip Planner will not change your Preferences.

Note: As you add more Campground Filters, the number of campgrounds that meet your criteria may be reduced or eliminated.  Map pins on campgrounds will be shown in a lighter color to indicate there is a campground in the search radius that does not meet your search criteria.  If your filters don’t generate matching campgrounds for an area, try adjusting your filters until more campgrounds appear.
