Greetings, I am currently in Aubrey TX about 30 mi N of DFW. The outside temperature is between 95-100. Is it typical that both A/C’s can’t cool down to mid 70s? They have run non stop and are putting out cool air. When researching I focused on Durango due to build quality and insulation. I presumed with all the insulation setup for cold weather it would also be that much easier to keep cool. I would guess it is about 78-82 inside.
Last week in Fayetteville AR it got into mid 90s , but I didn’t notice it getting as warm inside. Also curious if running air non stop will damage units. We are new to this and started full time abt 6 weeks ago.

I've always heard a/c is only capable of cooling 20 degrees below the outdoor temperature. It sounds normal to me what you are experiencing.

I was north of Houston last week and it was 100ish each day. I had both ac's running, they were cycling on and off, and my Durango Gold stayed around the mid 70's even in the heat of the day... I didn't touch them at night and it was 65 to 68 in the trailer every morning (which I love). Maybe starting the day a little cooler inside helped keep it cooler in the daytime.

Some shade will make a huge difference in heat load, so when two owners comment that should be considered.
That 20 degree difference often quoted is meant to be measured where the air enters and leaves the AC. The size, shape and construction of an RV can make a considerable difference in the performance realized.

From reading other post I read about covering heat vents. Can anyone confirm that heater return is the opening under oven? There is another louvered opening in bedroom below closet. This one is likely losing cool air so plan to use cardboard and tape up. Behind this one is the water heater that appears to be encased in styrofoam.

Our 380 takes time to cool, but it eventually does. Like said before, don't wait for it to get really hot, be ready for it, start cooling off before you really need it.

Our 384RLT seems to say cool in 90 to 100 degree temps with both air conditioners running, DW likes it about 65 to 68 most of the time even when it in the 70es outside Ugh, I call it the meat locker  Our main air conditioner runs at times all day an into the night non stop an so far we have not had any problems even thought I do worry sometime it seems to keep on ticking Safe Travels Chuck |

I was HVAC contractor for years. Actually starting and stopping is harder on a unit than continually running. They are designed to run, and won't burn up. That being said two AC units, given enough time should bring the RV down to mid 70's. If the inside is extremely hot when set up, I would think it will take several hours to bring it down to a comfortable level. On a side note, in a house an over sized system is worse than a properly sized because of lack of humidity control. For our purposes we want it to bring the temp down as quickly as possible when we set up at a new location.

Something else to try ... our Coleman Mach thermostats were analog (slider) and we could never get the temp set satisfactorily. We changed both out for the digital versions of the same thermostat. They look exactly the same and are a wire for wire exchange ... very easy and took about 15 mins each. Digital thermostats control set temps to plus or minus 1 degree. Made a big difference for us.

I am happy with the low to mid 70's inside the trailer in the middle of the day in the 100 plus degree Texas heat with no shade and the trailer out in the sun...
I agree with Ron that the original thermostats aren't real accurate. I just know that I need to find the spot I'm happy with them and leave them set there.

My son has a 355 Gold but has two 15,000 BTU units instead of a 15 and 13.5 and you can hang meat in there on 100 degree day. My 2500 has a 15 and 13.5 and we have had it in the low 70s on 98 degree day in direct sunlight. When we started going in and out a bunch it went up to about 76 and took a couple of hours to bring it back down. Now it had run all night the night before so it did not have to remove any heat saturation.
