The better option is to wire the third A/C completely independent of the coach and plug it directly into the 20amp 110volt plug on the campground post. That allows you to run two A/C units at a 30 amp site. And it keeps the third A/C completely independent of the coach in case there is ever an issue (a bit of insurance if you have a pet that you have to leave alone on occasion).


It is not that difficult to run an independent power wire to the third A/C and out to it's own separate plug/panel on the outside. Just be sure to use an extension cord that is heavy enough from the panel to the campground post.
