A few questions from a beginner about Fed/State Park RVing. 1.Although most Fed Parks do not have power/water hookups, is the same true for State parks? 2.Most parks have size restrictions. How strictly are these "maximum" length rules enforced? Do they give you a foot or two? 3.Although possibly to broad to answer, what type of "pad" are you likely to find in Fed/State-concrete, asphalt,crushed rock, unprepared,etc.? Thanks!
