Our 8.3 Cummins mechanical fired up so quick I thot something was wrong with our M-11
 
The M-11 doesn't take a LONG time to start, just noticeably longer than the 8.3
 
I don't notice any different in starting time with or without boost on our M-11, I just feel it's good practice to follow James T's advice.

Well, as usual I guess I am the odd ball. I can hear no difference in starter speed whether I use the boost switch or not and my coach typically starts immediately. I am now thinking that this could be due to my tiny engine, BT5.9, 230hp. See what you guys with the big engines have to endure.

George, did you sneak into the Lady's Driving School?

I was told early on the use the boost switch when starting to make it easier on the starter motor and all related components.  Higher voltage from all the batteries working means less current and faster starting.

However, because of this practice, I didn't know until some months after taking delivery of my pre-owned coach that one of the three paralleled AGM starting batteries had a shorted cell and was discharging the other two batteries.  Once I Replaced the bad battery, I have been able to start without the boost switch even after sitting without shore power (and without the battery maintainer) for a week or more.

OK guys, I now know for sure that Alton and the FOT shop was full of hooey. I disconnected my starting batteries and checked the engine leads to see if the inverter/alternator was supplying any power. It was not as all of our wise OLD members said. When I turned on the boost switch, the leads had power.

Shows what I know.

My little 230 engine still apparently starts easier than the BIG BOYS and with only two L/A starting batteries. Red tops are expensive.

That's a relief.  I was envisioning a disguise with a wig and housedress.

So does this mean I don't have to verify my M-11's oil pressure on my dash gauge at start because the electronics have already done it?

It is a simple reason why the mechanical engines always usually start quicker, it is due to the  computer engines go thru a sequence once  you hit the start button/key, once it goes thru checking oil pressure and faults, it then gets fuel to start.
