B+ motorhomes
I just bought a Trail Lite B+ 211s with 8.1 Chevy engine. This is my fifth motorhome (others range from an old 20' Vagabond, and three Winnegagos, from 19 to 32'. This vehicle is fantastic. I am...

If any fellow B+ folk (especially the many TL owners) can add info about the wiring of the batteries, particularly the emergency start (solenoid, relay, or diode), please have a look at this thread and opine away!

It may even be worth your time to repeat some of the voltage probes I did to see if you, too, have a similar setup.
FWIW ... I designed the battery/electrical system in our new rig to tie all three AGM batteries together. There are no dedicated house or starting batteries or any need for a battery monitoring shunt amp gauge.
Rather all three batteries are protected, to allow enough reserve for engine starting with an automatic low voltage cut-off. That way we get the benefit of being able to utilize 'all' the batteries for house needs while camping.
Because AGM batteries can tolerate a high in-rush of charging amps we also have dual engine alternators (265 amps) for rapid recharging.
There is no generator or solar panels either, if camping without hook-ups we use an automatic engine fast idle controller for recharging. For a test, I ran the batteries down to a rested state, automatic cut-off of 12.01 volts and then recharged them with the fast idle controller, it took only 17 minutes for the engine to return to normal idle. I can't state the true State of Charge, but based on experience I'd estimate that they were approaching 90% full.
