Your better off charging batteries with a stand along battery charger.
Your converter should be charging your house batteries I would check to see if plugged in and have 12v coming out of it and maybe you have the 110 circuit breaker tripped in your load center.

why does this Always happen the day before one leaves well i started the generator ran it for a while turned it off plugged back in just went to check the load center it was good hit my tester had 3 lights instead of 2 hopefully whatever it was is fixed ugh or i guess were not leaving until i take the batteries in to be tested

I would say your house batteries are OK if they are the ones that start your GEN.
They may just need to be fully charged with battery charger or just leave shore line plugged in over night than when traveling the engine altenator will take over if your coach has that option.

I you want to know if your batteries are charging, get a voltmeter and measure the voltage across the batteries.

Unplugged, your battery voltage should be between 12.2 and 12.7 volts.

If your plugged in, or generator running, or engine running, your charging voltage will be 13.4-14.8 volts.
