Is would be functioning normally. The A/C is designed to produce 20 degree drop from outside to inside.

I use a 12V electric fan on the floor of the bedroom door to circulate the air. It works well.

I have a 2008 27FB and it came with a 13k and as others have stated, the newer models come with a 15k unit. If and when it dies, I would likely upgrade to the larger unit but don't expect it alone would would make a significant improvement. I also live in the Lone Star Star State and am all too familiar with 100+ days and the best shade I can find is a tumbleweed. :-)

The 27FB has a lot of glass. I went to Lowes and found a roll of foil faced bubble wrap. I cut pieces that fit the skylights and vista view windows and placed them between the glass and blinds. That was much better than the blinds alone. I also cut pieces to fit between the glass and the dark tinted plexiglass stone shields. My Fantastic Fans have the snap in screens and so I cut a pair of disks to slip above the screens. During the day I close off the bedroom and now the rest of the trailer is much better when it's above 100 outside. Once the Sun sets I can open up the bedroom and the A/C cools it well.

I'm not an A/C engineer, but have heard the 20 degree spec mentioned before but believe it is measured between inlet and outlet. Any shade will help a lot.

Mine came white from the factory... Are you referring to an aftermarket coating like "Kool-Seal"?

When it's known that the day will be extra hot, turn the AC on early in the morning.

That gives you a head start on the cooling.

Yes, the interior will still heat up, but not nearly as bad.

Additional circulating fans, even small ones, also help.

A white roof coating is also a great help, but NEVER Koolseal, as it runs down the sides of the trailer when it rains, staining as it goes.

If yours came from the factory white, that's pretty much it. I painted the roof of ours with Kool Seal, and it made quite a difference. Before we did it, our trailer was warmer than our friends' 31'. After, ours was the same temp, even though we had a 13,500 a/c, and theirs was a 15k.

OK Gang,

Let's get this straight and end the confusion.

The 'Delta T' or temperature differential (18*F to 22*F) that is the basis of performance measurements in RV air conditioning is the difference between the cooled exhaust air measured at the cool air outlet or ducting and the return air measured at the inside return air grill of the A/C unit.

Neither measurement has anything to do with outside temperature......it is strictly a measurement of the performance of the A/C based on the INSIDE ambient air and the cooled air that the unit is producing. If the unit is properly assembled and sealed, there should be NO OUTSIDE AIR entering the coach thru the roof A/C.

In fact, if you have an older Dometic unit with a metal casing around the evaporator, you might want to get some aluminum tape (true HVAC tape) and seal all of the seams on that metal casing, just to be sure that no outside air is leaking into the evaporator. Newer units that have the all plastic casing don't require this, since they have a rubber sealing gasket in the plastic casing that does the job nicely.

Kent, do you have awnings on all sides? I know our Safari only came with a curb side awning. I added a big long one on the streetside that pretty much mirrored the curb side. That additional awning was what I needed to fight the sun. I always deploy all the awnings to minimize the heat gain.

I'm somewhat surprised to hear you have a 15K unit. I assume you are running it on the high fan speed.

I only have the one curb side awning. The main issue with awnings, I live in Amarillo. It is extremely windy here and I can maybe roll mine out once or twice a week. That pretty much leaves me with options that do not include window or side awnings. So far the small fans have helped greatly today. They move the cool air much better throughout the trailer. Tomorrow I will try the foil lined bubble wrap, that sounds like a real winner!

Thank you everyone for the great advice.

Best regards,

Kent

That's what I was trying to figure out. Do you recall if the white roof paint you got was standard, or did you order it as an option?

No point painting it again, in my book. Kool seal might be better, who knows? But certainly not "better" enough to do another coat.

I have run into this even with dual A/C units.

Hot, humid, windy weather is worst because you can't use the awnings and the wind leads to more humid air infiltrating. The humidity adds considerably to the cooling load. Also, windy weather isn't conducive to outdoor cooking, so there's a temptation to try to cook inside.

The lesson I took from this was to be more picky about site selection (where possible) and avoid unprotected sites with no shade during the summer months. Also, I try to have some cold meals available for days like this, that don't require any cooking.

I don't think the window film and so on really help much. It's mainly a problem of solar gain through the skin, combined with air infiltration.

Most all Airstreams came with white center roof panels starting at least in the mid-1990's, if not sooner. We've had our roof painted with kool seal for two years now with no peeling, flaking, or chalking. An added benefit is it covers the rivets up there, so if any were leaking they get sealed.

And in this instance, it doesn't help much that aluminium is an excellent thermal transfer medium. It absorbs and transfers solar heat very efficiently.

Maybe they had the right idea with the Argosies?
