Is there a charge to use the rv dump station ?

I don't recall seeing one. But i wasn't really looking either. I'd just call.

I'm assuming, yes, on this kind of service. You may need to call for assistance.

Yes.

I thought i saw a sign saying $5

Ni, they dont have that.

Nope

I dont think so

No, there is no dump station at Sideling Hill.

No

Don't know. Never had a use for it
