If "IF' you have a set of coach batteries that are bad it can stop everything, people need to understand when you are on shore power "It does not run off that for 12 volts system" it only charges the batteries! So if one or two of the batteries blow the other batteries will try and level the power between all the batteries now, so you could only have 10 or less volts, and most high need circuits (slides, leveling etc.) will stop running. They need a full 12 volts from the battery. Hope this helps you and other Happy Camping. P.S. will high need circuits it is always netter to do one at a time to stop blowing fuses and batteries up with the very high load on the system.

On a Berkshire, at least mine anyway, the jacks and slides run off the coach batteries. Not the chassis batteries.

silverback I believe you are correct on that when it's on TTs & 5ers.

I believe (not 100%) that on a moho when plugged into shore power it will run all 12v systems even if the batts are dead. I had a dead batt situation once and as soon as I plugged in I was able to run slides, jacks and all 12v were fully operational.

On my Dynamax DX3, the engine MUST be running to operate the jacks but, can NOT be running or the rear slide will not operate. The front slide can work with the engine running or not.

Hmmm... Wonder what the logic in one slide works, one doesn't is?

I expect it's some kind of a safety interconnect on the rear slide. Like the entry steps will retract when the engine starts (but will deploy if the door is opened). I believe that the two slides use different forms of actuation.

I believe it to be a bad idea to operate the jacks and slides simultaneously. First is the excessive current draw. The Berk cabin is not a rigid box. It distorts a little when the jacks are trying to get to level. This could be racking a slide mechanism. Last of all, the chassis and slide-outs tilt sideways during leveling. If a slide is close to a tree, it might bump it. IMO

That wasn't something they normally do, but with division of labor, if you don't coordinate closely, you can step on each others toes a bit.
But, when that breaks you down for 2 days, it's less likely to happen a second time
