St Augustine Campgrounds

DH and I have a 2006 Class A in good shape. Looking for a spot for several nights in St Augustine area. Anastasia SP has nothing available. Most CGs are pricy. Looking at Stagecoach, but their website seems to be anxious about any RV over 10 years old. Am I reading something into this, or do they actually enforce this policy (know some places do). There is nothing at all unattractive or "grody" about our RV. It was simply made in 2006! It's clean, well kept and acceptable to everyone who sees it. Please advise if you know about their policy, and if you can suggest another park. Thanks.
