Roof units

I've seen AC added to classic cars with good results but on a travel trailer... boxes always seem to end up sticking out of somewhere.
I have three main objections to roof units:
1. Totally ruins aerodynamics and aesthetics, particularly on a vintage trailer.
2. They are loud.
3. In my case, it would make the trailer too tall to store in my garage.

Not adequate

Of course moving the dratted thing in and out of the shower would be a PITA. But during the spring and fall you could leave it home. On the plus side, no holes in the aluminum. And they're not expensive.

My current AC is the Honeywell unit shown in your link. It has proven totally inadequate to combat the Texas heat, even when mounted high in a closet and vented through the refrigerator roof vent.

Not enough BTUs

I looked at these, but split system is 2.5x the BTU's for $80 more.

Not quite correct

The interior unit is also relatively big and designed for vertical wall installation with pipes coming out the back of it. There is not a lot of space inside an AS that can be used in that way. Sure, complete custom interior with the interior part of the mini split designed in could be done, but it is not an easy task.

Most residential mini splits operate on 240 volts, and there are a very limited number which run on 120 volts, the standard RV voltage system. The only 120 volt units I have seen peak out at 12,000 btuh. Often they are not inverter technology compressors, but the more conventional type, which makes them somewhat less desirable.

I can see some great possibilities for better RV AC units but no one is building them at this time. Adapting home ductless mini split units is difficult and questionable. Sure, it can be done, but it is custom work, and very far from plug and play.

The one duct "portable" units are very very inefficient in that they suck hot outside air into the RV to cool the unit and blow the hotter air outside. The two duct portable units, if you can find space for them and the dual input and output ducts make some sense, but again are not easy to fit into the interior of an Airstream.

Unfortunately there is no really good alternative AC systems for RV's, especially curved wall Airstreams.
The split system I installed is 12,000 BTU and 120 volt (only draws 8 amps max and is indeed an "inverter" type).
I will agree that installation is a PITA and far from plug and play. I am hoping the effort yields the desired result. Will keep y'all posted.

Agree completely

They just completly screw up the sleek lines of the airstreams even the new ones.
My sentiments exactly!

How many BTU was your old Honeywell unit? The one you said wasn't big enough.

It is the biggest unit I could fit in the closet. Nowhere near adequate, and the vent hose throws off lots of heat, even after adding insulation.

We have a split system in a church office. It has been great! The lines are flexible enough that you should not have much of an issue.

When installing my AC DEAUX(#2), rather than pull down inner skins, I did a ceiling penetration, ran power and condensate lines along inside of ceiling, concealing with an expanding "loom", not the plastic looking one, a nice black weave. My wife was going to make a fabric cover for it, but it turned out so nice, we left it plain.

I "penetrated" the shell at the floor, coming out in the water access box! The condensate tube lines up with the opening for the fresh water hose entry!!!! Slick.

For your front mount, I would come from underneath, like the turn signal umbilical enters the newer models. This would keep it water safe and allow you to run your connections up inside the trailer. You can easily camouflage them with thin wood or aluminum....

With help from a friend, I got the refrigerant lines vacuumed and leak free, then released the refrigerant to charge the system. Ran it for 30 minute test on both heat and cool modes. The outside unit is very quiet and the inside unit is barely audible. Max current draw is 6 amps due to "inverter" style compressor. Real world testing still required to see how it handles vibration while towing and whether it can handle the Texas heat but so far I am very impressed with this $700 unit.

I have a mini split in my garage. It does noticeably well in the heat considering the garage is uninsulated.

Just returned from vacation in Aruba. Virtually every building on the island has units like this. Probably saw over 1000 split systems compared with about 6 conventional window units and perhaps 10 full-fledged forced air central A/C units.

I applaud your efforts. Along with the Texas heat and your desire to park your vintage Airstream in the garage this is your only option. Great job. Motivation and persistance is the key to your success.

My window AC unit in our 66 Tradewind works fine for us and was really pretty simple.

Initial use report:
Just returned from a 10 day trip to ABQ Balloon Festival and Grand Canyon NP. Ran A/C lightly during the day and heat pump all night. Almost whisper quiet. Performed beautifully. Coldest night was 38F and trailer was a toasty 72 inside.
