In the last three days, the batteries have totally lost power after sitting for a day.
I jump started the motorhome, but have no idea what is happening.
Nothing I can find is left-on.
Has to be something big to drain all batteries in one day.
Any ideas?

Is it the coach batteries or the engine batteries? Coach batteries should be charged from the converter if plugged in to shore power. Is the isolation switch open? Simple question, are the acid levels good in any of the above? How old are they? If original to the Alfa, it just might be time for new batteries (ouch). Like Mike said, check connections at the battery(ies) for corrosion. Shine 'em up. I helped a motorhome owner once, there was a tripped breaker on the charging circuit. It was a tiny black button on a little grey box with 3 wires. One of which was a larger guage wire to the battery. Might look around. Sorry I can't offer better help.

I have an Alfa See Ya. I had to replace all of the coach batteries at their 6 year life span which is more than I had expected to get out of them anyway. Instead of going with brand new batteries (big money) I chose to get re-conditioned ones that were about a third the cost. They came with a 6 months warranty and are still going after 2 years. Something to think about.
Dig out your owner's manual and start locating places were there might be an electrical issue with switches, fuses, breakers, and the like. As was mentioned, there could be a charging circuit issue. If there is a short circuit somewhere that is draining the batteries, you most likely will have to take it to a shop where there is diagnostic equipment.
Battery terminal corrison has always been an issue on my rig even when I take steps to put a protective coating on the terminals. As mentioned, check your levels. The starting batteries are closed cell so that's not an issue.
Have a 2006 Alfa Founder's motorhome.
