We want to camp the weekend of April 23, and wife went online to see which sites would be best. We found some conflicting info - an rv review site says that there are water and electric hookups, but the recreation.gov site says just electric. Are there some water hookups somewhere so we can fill the tank? Has anybody run a camper off of 15amp or should we just use the battery? We just bought it last August so not a lot of experience with it yet (except at the beach where you even have cable hookups )
