Question
want to add top ac unit
who do you recomend IE Company of AC
and can you run it on 12v or must have it hooked up to 120 sorry probubly dumb ? but I am cluless
txs

Answer
I preferr Carrier, lighter, seem to cool better, has an easier filter to change out and clean.  Unfortunately, there is no 12v a/c unit available.  The load is way too massive for a 12v system typically found in a travel trailer. I would have to be hooked up to 120v ac
