AC replacement

Thanks, I have found the Dometic is under 13" and will work at a lower cost. I have a question out to one of the sellers about the control unit and plenum to see if the Advent will work with it. I noticed from looking at the Dometic plenum, they are very similar to what is installed in mine already. Where the real question lies, do the bolt holes in the clamp line up with the new AC unit, if they do then it will work.
