Coach is 2009 Marquis with rear bath layout. Still learning our one year old coach with 12,000 miles.
Driving in hot weather we have uncomfortable inside temperatures. Yesterday was 95 degrees outside as a high and the living room was 79, bedroom was 85, and rear bath was 90 while driving with Tstats set at 62, high fan and dash AC on. I have checked the in/out temp difference of the AC's and we are getting at least a 20 deg. difference. The AC's cannot keep up while driving on hot days. I realize the engine/tranny/road heat/etc. are big heat producers, but I don't feel we should be this hot.
Once we are parked and engine cools, the AC's keep us cooler, but even on the hottest days we seem to run out of capacity and the AC's cannot keep up (Full awnings, blinds and shades out).
Some remedies I have tried:
1. Had AC's serviced
2. Checked flow - seem sdequate but I would not call it strong.
3. Running fans to circulate
4. Watched generator voltage/amps yesterday Leg 1-120V/17amps Leg 2-116V/44 amps
Could I be missing insulation? Rear insulation not sufficient or maybe whole coach insulation is inadequate?
Is the coach creating some type of vacuum and is drawing cool air out while we drive?
Washer/dryer vent sucking all our air out?
Could the generator not keep up with demand?
Thanks in advance for any advice?
