<<Anyone out there convert (or even recommend) the� built in gas heater to run
intermittently off of a second battery?>>

As pointed out by Chris, with the auxiliary deep cycle 
battery, you can get more stationary time out of the BA-6. The fumes and 
noise are the negatives. 

This heater uses 10 amps and 1 pint of gas per hour on average. They run best 
over thirteen volts-a catalytic heater like an Olympian or Platinum Cat would 
be better for camping.
