Where is the nearest Dump Station for a RV. And Can I get water for my trailer at the campground?

There is potable water at the campground to fill an RV. Not sure about the dump station. There is one at Lake Hemet campground though. About another 1.5 miles down the 74E.

Iam not sure about a dump station since we tent camp and the area we stay at has a water faucet you may want to call the office to make sure.
