Well, you won’t if you have the Lil’ Stanker MK-IV holding-tank deodorizer fan from LSL Products. The roof-mounted MK-IV 12-volt fan replaces the original plastic vent-pipe cap, creating a slight vacuum that prevents tank odors from seeping into living areas. The quiet, low-current motor permits full-time operation with minimal battery drain, according to the company. The unit is 4 inches high x 6-3/4 inches in diameter, and includes a two-speed toggle switch and power-indicator light.
