When this happens to me, I merge the house batteries and the chassis batteries and then crank. You did not mention if you were merged or not. If there is a small non switched draw on chassis batteries, maybe they were a little drained.
One thing to try when/if it happens again. Turn the key on and watch the voltage meter drop, then check the voltage at the battery terminals. If it is a wiring problem the battery voltage will be OK.
Check all ground terminals, then positive cables. Ended up being a flat spot on my starter.
I've had corrosion inside battery cables. You could bend the cables and it would feel crunchy, not a smooth bend like a good cable would. Hope it works out. Tell Mary and Rudy and Carolyn hi from Cindy and I.
Will tell Rudy and Carolyn Hello. Bill I did merge and did not make any difference. I will check all ground and battery cables and everything else I can see that might make a difference.
I had check and tighten every ground and hot cable I could find and engine still not cranking after setting for several days so turned on the merge last night and this morning it cranked. Drove it to A & E Hydraulics and Batteries in town and had them put a load test on them and one failed. Specific gravity showed that it had two dead cells so replaced both batteries. They were almost 5 years old and I do not know what kind of treatment they had before I bought the coach 2 and half years ago. My six coach batteries were installed just before I bought the coach so those should be OK for awhile. Hopefully this will take care of this problem. The brand I replaced it with is Deka. I have a JLG lift which has 8- 8C batteries and the Deka brand has worked well on it.
there are just a few battery manufactures that make almost all the batteries in the usa. Delphi, Exide and Johnson Controls and East Penn.
they then label them for whoever.
i am not very brand loyal on batteries other than for who will take care of you if you have problems.

I agree Tom and I think Jonson Controls or East Penn Make Deka. I paid 168.00 per battery. 1425 cca and 440rc 1730 ca. These people have looked after me in the past.
Just changed out my Starting Batteries today. I agree with Tom! I shopped them and found 2 Sealed size 8D Starting Batteries for $300 total.
My House Batteries are TROJAN T105's and that charging system is completely separate from the starting system. This way I can have 2 different types for 2 different purposes.
in the spring i got my two 8d starting batteries at napa for like 160 apiece.
