Hi Rob. Can't help with your particular MH, there is a very easy way to find out though.
Get yourself a volt meter (every RVer should get one). With everything off and no shore power, check that chassis battery, it should read 12.4 - 12.8 volts, depending on state of charge.
Now start generator or plug into shore power. Take another reading. If it's now 13+ volts, your chassis battery is being charged.
If not, I would highly recommend a Trik-L-Start.
