We asked the dealer if we would be able to cool to 78 in FL and of course the answer was yes. 5 trips and 1 trip back to the shop and 80 is the best I can get. To even get 80 it runs sun up to sun down. So I'm hoping that someone else might know if I'm hoping for something that can't happen or is there a problem with the unit? The unit is a 2016. Any help would be greatly appreciated.
Not too long ago we had a lengthy discuss on AC systems in another thread. The link to the thread is:

Bottom line is you cannot determine whether or not an AC system is functioning by comparing inside to outside temperatures. You must determine the temperature split, or "Delta T" between the air entering the cold air return and the air coming out a vent/register. If the split is 15 - 20 degrees the AC system is functioning properly and it is a matter of time before the unit cools the coach. If the split is less than 15 degrees then the AC system requires service.

As a note, on my prior 30 foot class C I had a single 13.5K Dometic AC unit and it kept the coach at 70 degrees even when the outside temps were around 100. During those days we did limit the amount of time the door was opened because the cold air return was right above the stair well.

On my Challenger we have had a few days in the mid to high 90s and the 37 foot coach has stayed at 80 throughout with only 1 15K running part time. I have not tried setting the thermostat lower because right now my concern is not comfort but rather in dehumidifying the coach to prevent mold, mildew and odors between trips.

As a note, page 2 of the Airxcel Operation and Maintenance Instructions explains the temperature split and also states that the desired inside temperature is normally 80 degrees.
