Can a service truck pump a unit placed on a gravel driveway?
I'm setting up a portable toilet for a six-month residential construction project, a standard unit with a holding tank. My driveway was just redone with fresh, loose gravel, about three inches deep over a packed dirt base. The rental company is asking for truck access within 25 feet of the unit, but I'm worried their vacuum truck will sink into the gravel or get stuck trying to reach it. The spot is flat, but the gravel hasn't fully compacted yet. Has anyone had a service truck pump a unit from a similar fresh gravel driveway? Did the driver need to use boards or mats, or did they refuse to drive on it?
