    Keeping cool

    Have 2016 384gk.
    Haven't had it out in hot weather until recently when I was in full sun about 84 degrees. Both coolers seemed to be blowing cool air but inside could not get cool to 72.
    This does not bode well for Arkansas summers with 100 degrees.
    Anybody else with issues?
    Dealer says 20 degree gradient is all you can expect.
    Anybody else with similar issues or advice?

    Laughing - dealer is applying a little bit of knowledge incorrectly.

    There should be a 18 - 25 degree difference between the AC intake and the cold/discharge air, with a 20 degree delta considered typical.

    This means if the temperature of the air entering the AC intake (the area covered by the foam filter) is 95, the discharge air should be between 77 and 70 degrees. As the coach cools the intake air temperature drops and so does the temperature of the coooled air.

    Don't know what the humidity was but high humidity will impact how fast the coach cools off. Effectively the AC first removes humidity and then cools.

    We've been in our 379 in August in SE Missouri. It cools to 80, I don't like it much cooler in summer, nights it drops to 70

    Get yourself a infrared thermometer and check the discharge air temp. Dometic rep tested one of ours at the rally last year and declared it defective. Shipped a replacement to a nearby dealer.

    We bought a 2017 328 with three a/c units. When we were switching over from our old trailer to new trailer I had on the garage and front bedroom a/c units on. When it was time for bed I shut off the garage and bedroom a/c units and turned on the living room a/c. No air was coming out of duct work. I had to switch to fast cool, open chutes on side of unit. Had tech come check it out, and found out that they didn't hook up middle unit to air ducts. He repaired and everything worked great.

    Third AC unit may be the answer. Can a dealer install this.?
    I'll ask them. 50 amps plenty of juice for 3 units?
    Funny how a home 300$ window unit can cool a large bedroom but takes 3x?1000 for rv.
    Appreciate yalls input.
