Is there a RV sewage dumping station here?

Marty, at the Maryland house service Plaza I don't know if there is RV dumping hole!, but I can confirm that at the 37 mile post rest area there's a RV dumping hole, there also as adequate security, patrolled by MD state police, without the amenities that the MD House service Plaza offers, only vending machines!

There is not.

Sorry. I haven't seen any.

I'm sorry I don't know

I am sure there is

Try Googling where you can find it
