FamCamp vs civilian park
FamCamps are cheap. They are also frequently not on your route. This works out whether the savings survive the detour.
Round trip off your route.
Positive if the FamCamp has fewer hookups and you will run a generator or pay elsewhere.
Leave at zero to ignore. Optional.
Check availability before you plan around it. FamCamp eligibility and priority vary by installation and by your status, and popular ones book out months ahead, especially near the coasts and in winter. A cheap site you cannot get into is not a saving.
