mystery switches/ holding tank question
I am a complete neophyte at this so please excuse my ignorance.
I have just moved into a borrowed 2002 cedar creek for a long term stay. Some things are pretty straight forward others...not so much.
I see on the control panel in the kitchen that there is a galley holding tank, but can find no dump valve.
Additionally there are two red lit switches, one in the bathroom and one in the kitchen, what in the world is their function should they be left on or off? I am parked in an RV park and fully hooked up. I have the original owners manual which I have found to be pretty much useless except perhaps to find out if the wheels are supposed to be on the ground.
I would appreciate any useful information, tricks and tips that y'all can offer.
Thanks In advance,
