   We have a Truma Combi Eco in our Lance 1475, and it's supposed to   
   be installed so that it keeps the tanks from freezing (to a point,   
   of course).  My understanding is that it should heat on 12 V power   
   if propane is also supplied.  That said, when we camped a couple   
   of weeks ago we needed some heat while flatspotting.  It would   
   start up okay, but shut down after a minute or two.  On the other   
   hand, it would continue running if I hooked up the generator.  I   
   thought I had it set to gas only for heating (i.e., not electric   
   or mixed), but maybe I goofed somehow.
