Does it matter where the tanker comes from?
Brookhaven addresses appear on 3 of the 15 listings; the rest sit within 10 mi. Distance affects what a trip costs, since the truck has to drive to a disposal site afterward. What matters more is hose reach: ask how far they can run from the parking spot to your tank before booking.
