Been fulltiming for 11 years, private CGs, COE CGs, National Forest Service CGs, State Parks, Fairground CGs, National Parks and city CGs, Seldom call for a reservation way ahead, don't stay in parking lots and have boondocked very few times, our 40' length has only came up a few times. Usually you are told "no problem we have them all the time" if calling day of arrival, but some have no concept where a 40' RV towing a SUV can fit. I use the net, POI Factory imported into Delorme Street Atlas, and Passport America to find our stopping locations.
