Some years back, we had a long discussion on this board about using an inverter to power the TM's 3-way refrig while on the road. The motivation was partly the same - reluctance to leave propane turned on - and partly different - the inability of some tow vehicles to supply enough 12-volt power to run the refrig, and the resulting dead TM battery at the end of the day.
A lot of the discussion seems to be missing, undoubtedly lost in the board conversion that happened in 2002. However, there might be some useful content left.
