Fridge, even if propane will kill batteries (controls run by 12v), back lite light panel switches, anything. Only time I have ever used a disconnect switch is when I am not going to be around for a long time, I will shut everything down just for safety. This is with twenty plus years camping and several rigs. I just can't believe that Renegade is making coach's without a battery disconnect switch that will kill the batteries in a few days without being plugged in. If they are shame on them.
This is just my .02 from my experiences.
It's been pretty common over the 16 years I've been full time RV'ing to read hundreds of complaints by new owners of their batteries dying quickly. My Journey will die within 5 days, and I have to practice frugal usage of battery power. I've tested it. This is pretty common, even with the battery disconnects most models have because there are often sneak loads still on the batts, like the radio, tranni, and engine memories, all the detectors, like propane and CO are still live.
And there's also been millions of RVs made where the only charging for the chassis batteries has either been the alternator when the engine is running, or a weak 8-10 watt solar panel on the roof. So no chassis battery charging even when plugged into shore power. That's what the Trik-L-Start and Amp-L-Start and those other 'keep charged' devices have been about. There are models of RVs that include a float charger on shore power, or offer larger solar panels, but not all do, especially if they were the low end models.
You have been lucky that it appears you've been able to afford high end RVs over the years but even there, my '02 Journey (consider their high end model of the time) didn't come with a float charger for the chassis batteries. There is a tiny 8 watt solar panel for them but it outputs 1/2 amp when the sun is at it's brightest. Waste of real estate on the roof. Totally worthless that tiny thing trying to keep two large 12 volt batteries charged, more like a sales scam as optional equipment rather than a functional device.
So congratulations on finding and owning those RVs that did or are doing an excellent job of reducing or eliminating phantom draws on the batteries. Maybe that's the new normal...but I kind of doubt it. Too much incentive for RV manufacturers to leave out that equipment that may prevent phantom draws on their low end models.
