Ha Ha I know why.... After I got my coach home, I let it sit for 4-5 days, never using the disconnect switch. I went to start the genny, and click-click.
Two brand new 12 v house batteries dead. I didnt know I could just strart the coach and then I could start the genny. I jumped the house batteries with my car.

I have no inverter, don,t need one, but thanks for the tip about starting the coach!

Don, you are correct with your comments about how the coach was built. Coaches are built with the assumption inverter loads will be used (of those having factiry installed inverters). If an owner doesn't use inverter voltage or is always plugged in....he is not using the coach as built, so in this instance having less batteries will not be an issue.
yes? no?

I'll disagree. If your pulling in your 15' slide on a cold day with the coach listing to the side of the slide, you may wish you still had the batteries that were installed in the coach. Even though you could run your generator, the power still comes through the batteries. You would probably need an engineer to figure out exactly what battery size/amps would be needed in that situation. Hopefully, that's what the coach builder did during construction.

I know times are tough and people are always looking for ways to save money, but in my opinion, your batteries are not the place to skimp. The one time you need them and they don't work or are insufficient, it will probably cost you more than you saved.

MH's like most well engineered things are designed for the use that we the eng. beleave they will be used for by the ave. person. This use is often not what we thought it would be. This being said the number of batts. and total power reserve is always our best guess, So in some it is too large and for some to small. If OP is as stated always plug in and never dry camps the battery will always be at full charge so if this battery is 100amp hr capacity and can deliver 150 amps for 60 sec or so it will run there rigs fine under those conditions.

FYI: HWH room slides easily draw 135 amps when operated. That has the potential to wipe out that 1 12volt battery in no time. I agree it's not worth "cheaping out" on the batteries.

Going to only 1 12 volt may leave you without sufficient power to use the emergency start feature should your chassis batteries get discharged.

Four 6 volt and two 12 volt

You should have four 6 volt batteries wired in a series/parallel configuration to provide 12 volts to the coach/house.

There should also be two 12 volt batteries wired in parallel to provide 12 volts to the chassis (engine, headlights, tail lights, dash air, etc.).

There are many threads here addressing the different aspects of 12 volt systems in motor homes in general and Monaco's in particular.
