My brothers last 5th wheel had a Coleman Mach. On a 95 degree day it would only put out 75 degree air. In a poorly insulated camper with a lot of windows that is not going to keep it cool.
I have a older Travel Trailer. My Emerson AC will put out 50 degree air on a 95 degree day.
Someone on here started telling me that it was impossible to get more then a 20 degree drop in air temps. I was saying that my older AC would do better then that.
That led to a discussion about RV refrigerants .
About the time I was ready to give up and think that all modern camper AC are bad because of the refrigerant someone posted a picture of their Dometic Penguin AC also putting out 50 degree air on a 95 degree day.
Try the Coleman all the Dometic are junk .
P.S. Oh, and I just remembered. When I was trying to help my brother get his Dometic to work better we got up on the roof and took the cover off. The air flow design is backwards !! It draws the air through the condenser and then tries to push the air out through the sides of the cover threw the little slats . Not only is this a poor air flow design it also is flowing hot air over the compressor which is the hottest working part of the unit.
Stupid, Stupid, design. And, remember I'm a Caveman !!! Even I know this thing would never work well.
I apologize for the spelling and grammatical errors. I'm just trying to help by telling you the experiences I've had.
