Adding 3rd AC to 2018 Bighorn 3160el

I am considering adding a 3rd AC to our Bighorn. The current setup isn't keeping the living room/kitchen area cool during the heat of the day in this Texas heat. Has anyone installed one in place of the vent in the kitchen area? Will the current wiring support it? I am assuming that you can't run all three at the same time which I am good with. We would likely only run it with the living room AC during the heat of the day and shut it off and turn the one in the bedroom on at night. Any advice would be greatly appreciated.

have 3760 el - similar to yours - no 110 wiring there - tried to get it added when special ordered mine - they would not do
originally palnned to replace ceiling fan with unit - the attwood units - as it appears it wired with yellow 20a romex - - but found that if i set it to get really cold overnight that it is able to keep up very well during the day - for example this past weekend in the infield at texas motor speedway with 6 people in and out all day sunday in direct sun and very high 98+ camper never got warm and never saw temp above 74 inside

May have to start doing that. It will freeze you out of the bedroom but the living room is a sauna.

By the way, this is off subject but how did you upload the picture of your 5th wheel in your signature? For the life of me I cant figure it out.

so used to put fan to blow bedroom air down to liv room and helped - but found if you set living room down to 69 before bed its a icebox in am but is able to keep lv in low mid 70s all day with no issues

Thank you. That worked. It may be a little large but its a starting point and I can adjust it from there I think.
Just go back to to editing your signature and click on the corner of your picture and and drag the picture to a smaller format. Super easy.
