RV Repair: AC, jayco eagle, condensor

Question
i have a 2011 jayco eagle with coleman ac , is there a way to make it cool better ? They tell me it will only cool to 20 to 25 degrees cooler than the outside air temp

Answer
I wish I knew.  I have a 2008 Jayco and some days it seems really nice.  Other days it seems like it cannot get it together.  I notice it is on the days that it is most hot out.  I know on car A/C that if the engine idles, the air flow across the condensor is deminished.  When that happens the car cannot cool as well as when driving down the road.  Possible the same problem on the roof.  More air flow across the condensor means cooler air in the RV.  That would mean a fan that could blow air across that on the roof.  Worth a shot i suppose.
