Tank heaters?

This comes to you from the very nice Mesa Verde RV Park, just outside the national park entrance, where lovely snow is falling and the temp is 28.

We came up from Albuquerque, where the temp was 60.

All systems are go, and we're cozy. But it's made me wonder about the three tank heaters, which the manual for our 2012 FC27FB says we have.

In the best tradition of AS vagueness, it says there are three 12V heat pads which are switched separately to save the batteries. But there's no hint of where the switches are. Anyone know? Thanks.

If I understand correctly your size trailer using heating from the propane furnace. Only the smaller trailers use the electric system. Snow in Denver overnight also. Getting ready for a trip I left the trailer plugged in and put the furnace on at 50. Same thing coming back from Colonial a few weeks ago. Temps down to 10 degrees on the drive. Did the same thing. Only variance is that you have a 2012. Not sure when they may have gone to the heating duct method but looking at the online parts manual I only see the tank heating pad listed for the 23' and below.

The tank heaters are on the small Airstreams where the furnace is a direct vent with no ductwork thus no heat to send to the tanks. My 20' FC has two. The switches are in the bathroom on mine. Since they are 12 volt heaters, you either need to be plugged in to use them, or willing to kill your battery really fast.

I don't think you have them on your longer Airstream.
