Recently, with my MH winterized in my rv garage and connected to 30 amps through a Surge Guard model 34850 and a 30 amp dog bone, my transfer switch failed and over a period of a couple of weeks, drained my 6 6v Interstate batteries to almost 0.

So when the transfer switch failed, your inverter took over supplying 120VAC to ?
I'm surprised that in storage you had any 120VAC loads and/or the inverter turned on. Maybe it's a motorhome thing?
Or perhaps a 120VAC heater for winter storage?
On mine, I disconnect all loads (AC *and* DC) when put into storage, and just leave the solar to replenish the batt's self-discharge.
At the very least I would not leave the inverter on.
