I stayed at the Philadelphia South/Clarksboro KOA, which was a large campground in Clarksboro, New Jersey. Although the campground came with full RV hookups, a pool (which was closed for winter), a playground, and a lake, I thought the $60 per night price tag was high. If I planned on staying there for the full month, it would have cost me about $1,800, which is more than I pay for my Brooklyn apartment.
