We also live in TX and have a 27FB with a single A/C unit. If we can find a shady campsite, it is adequate but in full sun at 100° it is only marginally comfortable for the 2 of us even with all the awnings deployed and Reflectix in the skylights, roof vents and unshaded windows. Add some children and the heat load goes up as well as the frequency of the door opening. Shiny aluminum would seem to be a good reflector but it is actually a good conductor and that is why it is used in electronic heatsinks. Another attractive feature of an Airstream are the windows. In most floor plans there are many that offer a bright open feel, but all the glass and skylights admit solar heat. I am very happy with our decision to go with an Airstream but expect down the road to convert to 50A service and add a 2nd small A/C to cope with the Texas Sun.

Airstream may have been using white roofs for a long time. My '91 is white and looks to be original. We added a second ac after suffering thru a summer of being too hot.

excellent insight guys/gals! Now I am wondering if the 28' comes stock with 2 or am I going to have to special order...will likely get awnings all around while I am at it

If you're new to Airstream trailers, most models come standard with a "patio" awning on the curb side. An optional awning of the same length is available for the street side, and another for the rear. These are easier to deploy and extend only a couple of feet providing shade across the flat windows. I have seen some older trailers with short awnings on the street side that cover only the windows. The stone guard on the front window serves as its awing. The Classic and possibly some other models have the full set as standard equipment. If the trailer you want doesn't have them, they can be added.

4th of July test run

Summer before last, Saturday morning of the 4th of July long weekend (4th was Monday) the air conditioner in our house quit completely.

We set up camp in our 1966 model 22' Airstream Safari in the back yard and camped there until the house air finally got fixed on Wednesday.

Full sun location most of the day (tree shade only early mornings) with our Carrier Low Profile 15,000btu set on "low cool," the trailer never got above 75 degrees in the daytime, and was a chilly 68 at night. We both snuggled into our sleeping bags and enjoyed it.

When we put a new air conditioner on the Airstream, we considered the 13,000 btu unit, but since we live in Texas, we chose the larger one. At the end of that weekend, we were very happy with our choice.

This data is for a small trailer with a large air conditioner, but my opinion is yes, you can keep an Airstream cool in Texas.

The process was to clean and sand the area that would be painted white. Otherwise the paint would not stick. They used a spay on white gloss paint that dries hard, not the rubber type like kool-coat. It looks great when I get on a ladder to look at it, you can't see the white from the ground. There are no chips or pealing in the white paint in over a year. I think it does help in keep the temp down inside.

Here is picture taken from the back toward the front.

Here in Louisiana, I have a Duo-Therm unit on top of my 1979 28' Ambassador, but not sure of the size. Last summer I could only keep the temp about 15 deg. below ambient. On 100 deg weekends, not even my dog wants to go camping with me, most less my wife. What would be the largest unit available for 30 amp service? And, what all would be required to bump up to 50 amps, just in case I wanted to consider two AC units?

The temp of 97 here with all awnings deployed we hit 80 inside. No door open, cooking or TV.

Just a thought, I have been working on my Carrier 15,000 BTU unit on my 1976 Sovereign today. I installed this AC about 7 or 8 years ago. I started to have a problem with water/condensate leaking back down form the small pan area on the AC to the inside of the trailer. So I took off the cover and the inner plastic cover over the front coil and blower. I discovered why the water was not draining through the drain line it was covered with dirt and slime. But here is what I wanted to pass on that may be causing the poor cooling of your unit. The front coil was covered in dirt and dust from the return air side although I keep the filters clean. Also the cupped blades of the blower were filled with dirt and grime and this could not be good. The back coil on the fan side under the cowling was also blocked pretty much with dirt and grime and coil fins look like is starting to deteriorate. I cleaned everything by spraying simple green aircraft formula that is non corrosive for aluminum in the coils and then rinsed with water on low pressure. I could not believe what came out. I also cleaned the cupped blades on the blower so that is operating like it is supposed to. Also check the screw that holds the blower cage on the motor shaft. These can get loose and the blower cage just spins on the shaft. I made sure mine was tight. Put it all back together and turned the AC on cold, high fan. No leaking to the inside and condensate is draining to the outside through the drain line so I fixed that. But an added benefit is that the AC is really cooling much better than it has been and the trailer temp inside after a couple of hours is at 73. Outside temp here in Houston is around 90 degrees with about 70 to 80 percent humility.

So you may want to check out your coils and blower blades and see if this helps. I have heard that the lifespan of an RV AC is about eight years. So mine is getting to that point but it seems to be back in shape now so I will keep an eye on it for now.

I would bet that you have a 13,500 BTU unit. Duo-Therm now makes a 15,000 BTU unit that requires the same 30 amps.

Get a couple of good thermometers and check the inside temp of your return air at the grill where the filter is and the temp of the discharge air coming out. Regardless of the temp outside you should have an 18 to 20 degree temp drop between the return air and the discharge air. If not then the unit is not operating properly. See my previous post about cleaning the coils and this might help.

50 amp RV service provides 2 legs of 110v. In other words some 110v items run off of one leg and some run off of the other, with a 50 amp breaker.

yeah, nice pic...and great info....I called a dealer today and asked about the AC units...the salesperson may not have been the very most knowledgeable...he thought a 28' model with a single AC unit would keep it "very cold"....I think not based on what I have heard from near everyone...ill need two units...I hope the 28' has a stock unit with two...otherwise my "new on lot" vs. "new direct special order from factory" will be a much easier decision.
