We have been camping for the last few days with these 100+ temperatures with out any shade.
Subject:
2012 Mesa , does not have the new whisper quiet A/C. It does have the second air in the bedroom, dual pane windows , Yeti package, full body paint and no slide toppers.
Sitting in full sun with the temps at 95 degrees by 10am the inside of the coach starts loosing its battle with the temps. It will start the morning at 72 degrees on the inside.
Here are some observations I have made.
Stock registers.
Temp at first registers from rear A/C - 53.9 F.
At last registers- about 59 F. I do not have an anemometer but there is good air flow by the unit and drops off significantly by the last register. It does have the tent mod in the L/R unit which did improve the flow somewhat.
Inside wall temps range from 91F where the outside of the wall is in full sun to high 80s where the outside of the wall is in the shade-or at least no sun.
Surprisingly enough the ceilings of the slides are not that much different than the walls. I thought for sure they would be well over 100F with no toppers.
Outside temperatures:
This is where I was surprised. I knew the body paint would act as a heat sink. And as pretty as the body paint is, I never would have gotten it if it actually cost more than the other Landmarks. I would have been cheap just taken white with vinyl graphics-and probably would have pulled have the vinyls off. But that is a different story...
In the sun:
Light bronze or gold about 119F
Medium color brown 125F
Dark brown over 133F.. Thank goodness there is not much off that on the sides.
In the shade or at least off-sun exterior temps all ran a little more than ambient temperatures to +10 degrees.
The inside front and rear caps have the greatest temp difference. A tribute to the Relectix???
Results: By mid afternoon the inside temp of the trailer is about 84F downstairs but the upstairs is still around 73F. Considering the outside temps. I would say the 30-40 degree drop in temperature between exterior and interior is acceptable. I do belive there are better products that could be used rather the white extruded polystyrene.
For the most part after talking with several other owners I guess it is what to be expected. I am not complaining because once the ambient temps drop down to 95F the trailer can keep up fairly well.
It has made me think a little about the duct work in the trailer. The worst shape for air to flow through is a rectangle or square. Air flow does not like 90 degree corners.
I also think there is potential for the airflow to be much better at the registers. There is enough room with in most of the existing duct to run round duct. The problem there is not enough room to incorporate the registers with the round duct.
I also think that a lot of volume is lost when the air comes out of the airbox on either side and has to split front to back. I am thinking something similar to the tent to help make it's split might improve airflow a little.
