I read somewhere they had some Brisk units that were low on coolant from the factory and I'm starting to wonder if I have one of those units. I definitely have that unit, but it hasn't been checked.
82F when it's 95F outside doesn't seem right to me with both units going, and having it at 65F during the night.
If you sun coming on through the windows you might want to try blocking that as well - reflectix does work well here too. Not sure how your rig is built - I would think you have enough insulation and what not to keep the cool from escaping that quickly.
To your other point on how the A/C units are performing - have you check the temp coming out of the main vent. Might pop the cover off and measure outbound and inbound - you could be sucking your cold air straight in due to a leak.
I know the back unit will freeze us out in the day but the front builds up all of the heat and sometimes will get to 80 or more in the very front. Now realize we have a MH with all that glass up front - we did put up some reflectix that helped a whole lot.
You know the other thing I thought of was buying a little portable unit - especially when our rear A/C went out and we rough'd it for 6 weeks, not wanting to put the MH in for service due to the down time.
So how does it do at night when the sun goes down? Cold, cool? ?
Hope all of these suggestions helps. Let us know.
