Make sure the black and the grey tank both have good vents to the roof of the trailer. The can share the same vent line (1.5"{ ABS is good) and it can be connected to the drain line from the sinks to the tanks. The vent line will allow the sewer gases to escape vertically from the tank, and will relieve any pressure inside the tanks that might force gases past the P-traps. Don't forget that you always have to refill the P-traps after dumping, the suction sucks them dry.
