I have a 1988 Ford Econoline chasis Class C Motorhome. My wife was recently returning home in our motorhome and had all of the gauges fail, the seatbelt light came on and the engine shut off. She ha...

I agree with the other comments that it is possible your voltage regulator might be a separate component from your alternator and it could be at fault, or the wire termination connections to it could be at fault. I would start trouble-shooting by first locating your voltage regulator.
If the regulator is integrated side the alternator, the next step would be to determine if your alternator output amperage is adequate for a motor home and not just a van. It might be too small for the job and is faltering.
One additional consideration is that the isolator could be stuck on servicing the house batteries, so the chassis battery might not be seeing a charge from the alternator. And if the house batteries are terribly drained, they just might be pulling down the voltage reading to the numbers you shared.
