Question about tank heaters

[revrusty]

Curious about the switches for the tank heaters on my 30rkd. One for fresh, one for grey, and one for black. BUT I have 2 grey tanks, the second for the galley. Is there a tank heater for that one that is controlled by the single switch? Or is there a switch located in some other area than inside the front compartment? Or does it not have one.
Rarely have reason to use them but it got down to 16 degrees a couple nights ago in this part of Kansas and I turned them on. Had no problems when dumping tanks today.

Thanks as always for any input!

Did I finally come up with a question that stumps everyone? Since I had no problems I guess there is a tank heater under both grey tanks. Hopefully done with teen digit cold for the season. Happy holidays to all.

I subscribed earlier to your thread because I was curious. Our TT is the same, 4 tanks but only 3 switches. I assume my two gray tanks are on one switch, but I have no idea. My general principle is that it's to move on down the road if it's that cold. LOL.

Usually these folks can find the answer for anything. Probably will for this sooner or later.
I was in Kansas bird hunting at the time so I didn't want to leave!
Guess someone will te me to turn them on and stick my hand in the tank to see if it's warm.��
