William, the Trumas look very nice, and exactly like what I am ultimately looking for. I saw 12V listed in addition to the 230V on the spec sheet, but I believe that is not related to the cooling power draw.

Right now I am leaning toward something like this: http://www.dometic.com/b5e39f4c-034a...16558d4a.fodoc

You might consider something like this as well. Don't know what the prices would be: HSA 16,000 BTU/h 1kW 115V/60Hz/1-Ph - Marineair

I am trying to get resolution myself so that it can inform any floor plan modifications or frame modifications.

Hope someone can find something good. I need to start making calls and emails this week to vendors.

Matt

I'm a little weak on the subject, so here it goes.

The "Truma" looks like a really cool system that would work well in a bunch of trailers. But, it appears to be 240v. So the question becomes, it there a model like that in the USA, how does one convert to 120v, etc...

Enjoy,

Split for an Argosy Minuet

Thanks to all that have contributed. I have a '78, 6.7 Argosy Minuet. The interesting thing is that it has never had AC in it. Cam that way from the factory and lived most of its life in Maine. In New Mexico and many of the places I travel, AC is a necessity. To date, the LG that has some history of use seemed the best choice with a balance of cost ant ease of installation.

The recent posts show the Truma and the Dometic split for a truck show great promise. I especially like the Dometic's compact external part.

Has anybody actually installed one of these or anything other than the LG and could they share their experience?

Greg

O-K....Am I missing something here? To get rid of the roof mounted A/C unit why can't a portable 8-10K BTU room air conditioner work? It could be vented thru the floor or side wall. Just a thought. edc

Sure you can, but one portable A/C will only work for a small trailer. I have done this for my Tradewind. I mount a portable A/C unit in the side window when I need it. The rest of the time it rides in the bottom of a closet.

Longer trailers would need multiple portable A/C units or a split system that would allow more than one location for the air handlers. Remember that new solutions have new problems. That is really what this thread is all about; identifying the new problems and how to solve them. It is not easy.

Thinking about the portable units I could install them much like a window unit in a fixed installation in the trailer vented through the floor or something. I guess they may work much like the product I'll mention next but if they are designed for stationary use in a house or apartment I'm assuming that they are put together differently. The cost for a couple of these free standing ones isn't so different that I'd be tempted especially if I have a blank slate for installation.

Next up I read the install sheets for the LG splits and there's a lot of warnings regarding vibration and that the unit must be installed on a level surface etc, which although I appreciate that it isn't going to destroy the unit immediately does make me less than encouraged. Still not ruling it out completely though, I could even start to like the big external unit if I had it chromed.

I'm hunting for more info on the Dometic ASCEQ14. It's listed in their file I mentioned earlier in this thread but I'd skipped past it thinking split was the way forward. It's one of their self contained units that vents through the floor, runs solely on 120 Volt power, provides up to 14,000 btu plus heat and runs off a 2.5K generator. I found a used one that sold for $375 and the Dometic site mentions that they are cheaper than their split systems so it sounds positive. It gets installed with ducting to take the cool air up to where it's needed but that's a given with all of the units except the splits. On the up side the install would leave no visual clues on the outside of the trailer and I could even consider two smaller 10k units instead, one fore and another aft to ease losses in the ducting and still run both of my Honda generator.

I like the look of the Dpmetic SC14K as well. The external could be mounted forward in the underbelly spare tire spot.

or in the tail section like on the '55 in Colin Hyde's shop…although I see that's a 10k unit.

Just for completeness and to answer a question about running a 240 v unit I saw this in the UK, it's a Dometic HB2500 under couch AC unit and I saw an optional accessory that allows it to run off 12V… So not many btu's but it's another unit that's out there.

HB2500 Air Conditioning Unit

Experience the world′s first under-bench motorhome air conditioner with genuine heating function! Regardless of whether it is tropically hot or unpleasantly cold outside: the climate inside your vehicle is always just right.

RV Trailer Air Conditioning and Heating

Another one; but this bad boy gets installed outside the trailer…. I haven't bothered reading the install stuff but I guess it's built up a bit more for life on the road.

Nordic Air

Another option although the website looks a bit military. Nice to see you can have it made all aluminum or stainless though :-) I don't think I want to know how much these would "retail" for.

Never used R 407C don't know anything about that coolant.

I finally was able to talk to Danford and was told that they DO NOT do RV installs and the sales person was rather rude, anyway the biggest system they have with a 115VAC compressor was 10k btu.

Which ever systemI use I would prefer R134a.

My current fave, the Dometic self-contained sleeper cab model ASCDQ14 uses R 22, no idea if that's good or bad? I just realized that even when I don't have 120 and can't run the genny that I can run it on fan only mode drawing cool air from under the trailer in and vent warm air out through a ceiling vent at the other end of the trailer which would be better than nothing (or FF's) in a state park on a hot night.

more info on it here, http://www.dometic.com/FileOrganizer...s%20L-2596.pdf

Should I be more concerned about the refrigerant?

William, I need to ask at least for my own edification. Again, I am sure that I will demonstrate my ignorance, but looking at a couple of these options:

- For any ordinary window type unit, would I have sufficient ventilation if I attached the rear of the unit to the large vent coming up from the fridge? I would like to put it above the fridge.

- For the UK/Oz 220/230V models, is it possible to use a voltage converter safely to change it from 220 to 110V? It doesn't seem like real viable solution, but, why not if one could find a robust converter? Used the plenty while overseas for long term if static use.

Anyone have sufficient HVAC or electrical expertise?

Thanks,

Matt
