Customer loses remote Dometic loses customer (Fantastic Fan)

The switches and speed control for a Fantastic Vent can be purchased on line or from a good electronics supply store. I have two FVs in our Winnie and unlike the one in our Bounder, they have no fan reverse switch. If we were not contemplating sell our rig, I would just buy a DPDT (double pole - double throw) switch and install it without buying a factory switch from Dometic.
