My 2006 Jayco has a "power vent" fan located within bathroom. Much like the one recently installed at: http://www.jaycoowners.com/showthread.php?t=1413
Great fan but at times, its RPM is way too fast. When fan is ON and one tries to open its bathroom door, it feels like the door is being over sucked into a closed postion. IMO, wa too much RPM / vacuum inside its small bathrroom room.
What switch, resistor, ??? can be installed to create a 3 speed fan? For example, OFF, Medium or Fast (full) RPM speed. Currently, its factory default is either OFF or Fast speed. Would be nice to have option of slower RPM fan.
