   Okay, that should be within my rudimentary skillset.  Is it as   
   simple as putting the multimeter probes on each battery post while   
   starting up the furnace?   
      
   FWIW, the battery also has a nice bluetooth interface that gives a   
   lot of detail about its state (including voltage).  Don't recall   
   seeing the voltage drop much from the nominal 12.8 V, but then I   
   haven't really watched it much.

   Yeah, that was my thinking too.  I'd like to be able to camp in   
   remote National Forest areas in the Rockies, but if the furnace   
   won't run on 12 V that may be a non starter.
