UPDATE ON THE AC ISSUE:
After pulling every return, every supply vent and re-taping, pulling the shroud to check any damage at the roof top level, here are my results.
Set unit daily to 70 degrees first thing in the morning. We have had days were highs are 79 up to 89. Zone 2 continues to put out mid 40's air and remain at 70 and cycle on and off. Zone 1 continues to put out 53-59 degree air, return temps in the 70's and living room stays 70 till about noon and then within 3 hrs it is 75-76 and remains that way. Tried with all blinds closed, ceiling fan running, ac fan on high. Have noticed slide ceiling temps at 80+ degrees. Great CFM and always over 18 degree + difference in return versus supply so local Dometic rep says no way anything is wrong with unit that it would be either insulation issue or air leak. Even put my remote imaging camera into both returns and several vents and saw nothing alarming. Even sticking handheld thermometer in return notice no variance in temps. Very perplexing as it just seems I am destined to get no better than 75 even on days outside temps at 80 and even 90. Not sure if any other Alpine or similar 5ers are getting same results. I even had my parents check their 2010 Alpine and it has same Dometic setup with heat pump and ac and they are not getting same results. At a loss....any advice other than suck it up!!!! Thanks!
Also..not a sensor issue as the handheld thermometer matches thermostat sensor temp!!!
