I'm guessing the "you need a bigger inverter" suggestion means they were using the built in transfer switch in the inverter?
'Bigger' wouldn't be the word that comes to my mind if referring to a transfer switch, but as I said, RV techs don't know a lot about this stuff.
I was thinking "bigger" referred to the amps the inverter's built-in transfer switch was designed to handle. With an inverter less than 30amps, maybe they figured your "30 amp coach" couldn't be be fully supplied.
I had a similar concern, didn't want to buy a larger inverter (cost + standby power). I had a choice between a smaller pure sine wave (1800w/2100w surge) and a larger modified sine wave. Also due to the discussions and info here, I went with PSW, which is better for our needs.
You remember, thanks ;)
Obviously, I'm just speculating as to 'why' the techs suggested a larger inverter ;)
