With the weather in the South getting hotter, I had to run the dash A/C yesterday. The temps topped out about 83 or 83, but even at that my dash A/C could barely keep up. The air coming out the vents was fairly cool, but nowhere near as cold as in a car or pickup. I did not have a thermostat so I don't have an actual reading, but I would assume mid 50's.
Is there a problem or is this normal and am I going to bake in the summer while driving?

John,
I had the same complaint, which I voiced to Newmar when I was in Nappanee last summer for some repairs. They stuck a thermometer down the throat of one of the dash A/C vents and told me that it met specs, which were something like 10 degrees F cooler than the input air. Not a very "powerful" air conditioner. The Newmar techs told me to just run the generator and turn on the front coach A/C.

Pretty much the nature of the beast. Doesn't seem to be that important to the manufacturer. Did have a much better dash AC in my last coach(Bounder).

Some things to consider;

Your dash AC operates no different in your MH than in your car! In the AC position it is cooling outside air drawn through the heat exchanger to cool 45' of MH. In MaxAC it is drawing air from the entire interior area of the MH and trying again to cool down 45' of MH. Sounds like the cooling spec for you MH is about the same as it is for a auto, unfortunately the volume of air you are trying to cool is considerably different, hence the suspected lack of cooling efficiency.
It has been explained to me by various RV manufactures that to cool the larger volume of air in your MH it is most efficient and economical to use the generator and roof AC's. I have had some luck with cooling the unit down with the roof AC's, then switching to the dash AC to maintain the temperature, works reasonably well depending on outside temperatures.

Some people have had extra cold air vents added in ceiling for more cooling up front while using the roof top AC's.

Gee thanks, bunch of Little Mary Sunshines here....

I was really afraid this was the answer I was going to get, but I can always hope.

CSX4350 There is way. Go to WalMart and get your self an expansion rod and some curtians/drapes hang the rod across the open area from the closed slide[s]behind seats and this will reduce the area that needs to be cooled. Downside Front area is nice and cool, but the area behind the curtian is a little warm.

Same problem with mine...and in the south going into the sun with all that tall windshield, there is NO WAY I can stay cool unless I set up a squirrel cage fan and blow it onto the windshield, and then it's only a slight help..

Ok lets try this, here is a discussion about poor cooling from coach AC and the add of a ball valve for better cooling because the control valve was allowing hot water for heater entering the heater core defeating the AC side of AC/Heater unit.
