Summer heat

I have a 2016 rockwood 8315. With the 15,000btu ac. It's currently 97 degrees out and sunny. My inside Temps are at 91.2 degrees. Is this normal? That my ac can't really compete with this heat, that I have 2 personal fans blowing just to stay slightly better than unbearable?

I have the 3065w Windjammer and have similar issues. We just came back from Cape Hatteras. Was not super hot just mid 80's, but no shade at the beach. A/c ran constantly, only cut off after the sun went down. It did keep the trailer at 72 degrees. We keep 2 small fans going to move air. The a/c is loud and its a relief when it finally shuts off. But it does not stay off for long. I love my Jammer, but it struggles to maintain a desirable temp. But with 30 amp service it can only support 1 a/c. If I ever update the next one will have 2 a/c .

There have been posts where AC was not cooling and the OP found that the ducting had pulled away and insulation was missing inside the AC under the plastic covers might be worth a check

You have one or two AC. If only one 15000 it will struggle with the size camper you have. I have 2 AC and it keeps it cool to what ever we set it at. Later RJD

I have only 1 ac. In the front living area. But even if I close it the door to back half. Temps don't change really even closing the back vents.

I wanna say I may have frozen up the coils or whatever. I know I had this happen once in my house and it required us to shut of ac and just run the fan all night and by the morning all yhe ice had melted around it and worked fine. I'm wondering if the same happened here.

I also bought an infrared thermometer to check Temps at the vents and inside the ac to make sure there isn't loss of cool air somewhere within the main unit.

My 8325ss 35 ft. Has 2 a/c. Last week the temp outside was 94 and I managed to stay 74 in the trailer.
After the sun goes down it will go to any setting. We like to keep it around 68 at night and one unit will take care of it at night.
Two units at night will freeze you out. Just guessing you could probably get close to the high 50's at night.
Our night temps here have been staying like 84 till around midnight and then it's about 76 in the morning.

As hot as it is, and with a roof mounted A/C as opposed to a home central A/C with the evaporator coil inside the house, turning your RV unit off for 20 to 30 minutes should fully defrost any icing.

From 95 degrees my 13.5K Btu will take about 3 hrs to cool this camper down to 76 degrees. I open the powered vents and suck out the heat 1st, then close all the vents. Recently, I came across some sheets of 2" expanded polyethyene foam and cut blocks to wedge into all 3 vent openings and especially the skylight opening in my shower, which is 2x the size of the vent openings. It was amazing how much heat you could feel radiating through those openings as you run your hand along the roof. I cut the blocks 1/4-1/2" larger than the openings so they would stay put. I see Camco make the pads for the vents for about $9 if you can't come across the foam on the cheap.

I let the salesman talk me out of two air-conditioners. The byproduct of that is that I have 30 amp service. Will never do it again on this size trailer. Our trailer is 32 foot inside and I have one 15,000 BTU air conditioner. On a 90 day degree day it will not hold temperature below lower to mid 80's inside. At night it's fine. Parking under tree shade helps though. And then there's the byproduct of 30 amp service. If you're running the air conditioner you cannot run a hairdryer or curling iron. Not a problem for me but a big problem for my wife. Actually thinking about a trade to get the "stuff" we have learned is important to us.......
