I'll chime in to say that I keep mine plugged into 50amps in the driveway all the time during camping season when we're not actually camping, with fridge ON and usually at least the A/C fans blowing on low....if not the A/C fans, then a floor fan plugged in and blowing to keep air circulating. For me, camping season is usually March through the end of November, so 9 months out of the year she's plugged in. I'm running a single 12VDC RV/Marine battery from Auto Zone as the house battery and so far it's never failed in the past 4 years. I'll probably replace it after the end of this coming season. The other months, the pink stuff is in the lines and she's stored under a shelter. The chassis battery has a trickle charger connected so it gets a conditioning charge while not cranked and driving down the road.
