When you are plugged in, your meters will show "full" even if the batteries are dead, because your meters are just showing voltage. Your converter will be doing 13.6v and a full battery is 12.7v, so the meter thinks the battery is full seeing that voltage above 12.7.
If for some reason you have the battery disconnect "open" at home, the batteries are not getting any charge from the converter, but the rig's 12v systems will indeed be 100%--from the converter.
Meanwhile the batteries are dying. So you get to the campground and try to use the batteries and they are in sad shape. Plug in, and you are good again--converter on the job.
BTW, a trick (for trailers) so you can use a low battery on arrival to run the jacks or whatever before you plug into shore power, is to leave the 7-pin connected and leave the engine running, so the alternator can keep the voltage up. I suppose with a MH you need to push some button or other to get the same result. :)
100% is from the meter, after the shore power has been disconnected. . .
Battery cutoff is "closed" and i checked all the wires and connections to see if they were tight..
