Hey David, so the easiest solution that is very cost effective would be to go with the Advent Air for Dometic Setups part # ACDOM135. This was specifically designed to replace Dometic units so the install is as easy as it can be since the wiring plugs right in and allows you to use your current controls/thermostat.
Now if you were wanting to "treat yo self" the absolute best solution would be the Furrion Chill # FR86SR which is also designed to replace Dometic units. We tested all of the units we carry and we found that the Furrion units are the quietest and also blow the coldest. My parents put one in their camper and really liked it.
