thanks for all the info. my genny is a ryobi 1000 watt model, output 900W running. I believe my converter is 30A I'll check to be sure.
so question ? the converter charges the battery only and actually doesn't directly supply the 12V power to the coach ?
and yes propane for the frig. my biggest concern is cold weather when I'll need my furnace, I'm sure that will be the big hit on the battery

The converter and the battery are basically connected together in parallel. The output current from the converter when hooked to AC power and using DC power is split between charging the battery and powering whatever DC things are in use. If you're familiar with basic circuit theory, this is a straightforward application of Kirchhoff's Current Law. If the current feeding the RV circuitry is greater than the converter can produce, the battery will be discharging to supply the extra.
(There almost certainly are some fuses, wire connections, disconnect switches, or other elements between the converter and the battery, but these can be safely ignored for this basic analysis.)
