This is a demo showroom model built in January 2020.
The covid shutdown closed the showroom.
If this coach wasn't plugged in or in direct sun then these AGM's might be toast. We'll know soon.  I'm getting knew ones installed next week and I'll have the old ones tested.
I've checked the connections and circuit breakers. All good.

You have done what you can do, the new batteries will provide the answer. Glad that they can be replaced under warranty without returning to LD.  Good chance the floor model experience, and being shut down for a long period damaged the batteries.

Good luck and enjoy your new rig.

It's been a good rig so far.
I'm really liking the 7.3 liter power and the 6 speed transmission.

Ted, is LD or Lifeline footing the bill?

Yaahh.  I purchased lifeline AGMs and was very impressed with technical support and the battery itself.  They are heavy so it is great they can install them for you.  Like all installs done by someone else make sure they do it right.  Don’t cross the positive and negative cables, if possible, as wear between touching cables can give undesired results. 

Hope your troubles are now behind you.  Enjoy your LD!!  Glad to hear the new engine is grand!

Frankly I'm surprised you can run the refrigerator off electric when shaded.  On our 2000 MB, the fridge puts quite a draw on the batteries.  We always run the fridge off propane, unless filling for gas, etc.  Is this common on the newer rigs, to be able to run fridges off electrical while parked?

"I'm surprised you can run the refrigerator off electric when shaded."

I believe what Ted meant was that the DC voltage was dropping so low that the fridge would not work on propane--that is, its controller board couldn't get enough 12 V juice. As far as I know, Lazy Dazes have never been factory equipped to run the fridge from batteries, since the 30+ amp draw would quickly drain them.

Correct. On propane. The control board wasn't able to operate at 10.6VDC understandably.

Just an FYI...My 95TK was 3 way power sourced.
I never used the 12VDC much because of the drain.

12VDC.

All good now with these new replacement batteries it seems.  I'm loving how the solar keeps them topped off.

Our old 1983 LD’s refrigerator drew 23-24 amps, when operated on 12-volts. It was only operated on 12-volts when we were driving.

Thanks Andy, that makes sense.  We're happy to have had AM Solar wire up our inverter so we can switch to electric when needed (e.g., at gas stations, when filling propane), or even while driving if we want, but yeah, that's quite a draw! 

And it may just be my perception, but I'd say the fridge stays colder on propane than on AC.  That surprised me too.
