Anybody use a Portable Airconditioner?

I have a 22' 1964 Safari that I am about to start. Has anyone used or considered using a "portable airconditioner" in their camper? Possibly mounted in a cabinet with the 4" port ducted to the outside through an access panel? Thoughts? What size AC unit would be good for a 22' trailer? I am in the Southeast and will take it to the beach and warmer places.

I can install a rooftop unit but I think it compromises the look of the camper a bit. If I go that route does anyone have recommendations for best funtioning/loooking AC unit?

Thanks for any input.

I tried a portable A/C unit for a trip a couple of years ago...here's a couple of pics of our set-up. We rarely camp in areas requiring A/C...so I didn't go to the effort to build it in...and I'm glad. It worked okay, not great - but okay, although it had trouble cooling more than 15-20 degrees cooler than outside during the heat of the day (it was 90-95 outside and humid!). The biggest problem being the exhaust hose heated up the space as much as the unit cooled it down - although it got caught up at night.

Another year since then, we went with the window unit (removing it for travel) and a series of filler panels to hold it in place. That worked much better because it exhausts directly outside. I may have some pics somewhere - but you can get the idea.

<on edit> I found a picture of our window A/C installed here. I worked much better - it's the right solution for us for a temporary (one trip a year) fix.

Several have installed window-style A/C units under dinettes or beds that have a pull-out panel for exhaust & ventilation. That seems to work well too...if we ever do decide to add an A/C to either trailer, we will do something similar. Here's a pic.

Knoxvegas,
Our rooftop went kaput just before we were headed out for a trip last summer. In a pinch I picked up a portable AC from a box store as a temporary measure to get us by on the trip. Ran a temporary exhaust duct out through one of the storage compartment doors under the bed. It was a 15K BTU and it really struggled to keep the the trailer cool--it ran ALL the time. It was also so noisy we could hardly tolerate it--the rooftop units aren't exactly silent but this thing was loud.
I would suggest that you try a different route like a modified window unit or something else--was not impressed by the portable units.

I hate the look of it though...a big wart on the front of the trailer! Very "trailer park" IMO...but it did keep us cool ~

Shari,

How cool is the pull-out panel?? That seems like a great solution.
I have spent some time going through your "Its a girl thread" congrats on the gret work.

Good to get the feedback from all on the portables too.
The PO has mounted a permanent wall unit where the kitchen window is.
That will have to come out. Will get picks up soon.

I also have a question posted about tankless hot water heater on that section if you all have input.

What would be the proper place to start a thread for the whole project?
Under the model/yr in the trailer forum? That does not seem to get much traffic?
Anyway, pictures of my project will go up this weekend. Finishing a deck and fence and hope to get started in next 2 weeks.

The way to go

For my 1966 22’ Safari, I use the setup below. Pretty simple, get a folding aluminum table from Wal-Mart/COSTCO, take out the two pins that hold the two pieces together, cut legs down to length needed, put a 90 degree clip on the end bottom of the piece that sits on the window to hold it in place, put the A/C unit on top, then put three pieces of Plexiglas around the A/C unit on the inside that can be held in place by screen clips, then take “pet screening” (the vinyl type from Lowes, doubled up) and make a cover that is held in place either by Velcro or the strong type paperclips that look like a “V”. Since a 6000/8000 BTU home unit only pulls about 640-860 watts you can use the standard wall socket (no breaker upgrade needed) to run the thing. I can pull it out of the car and install it in less that 10-15 minutes. You could run two of them(front/rear window) off a 2000 watt Honda genset, running it off of the propane in the trailer all weekend!!

It’s easy to install and cheap!

Also, here's a link to a same type thread.

I found a window unit for slightly less than a new motor for my Bay Breeze (which may or may not "fix" the Bay Breeze). I am in the process right now of fitting it into the curb side window of my '61 Safari. There is about 3/64ths of an inch to spare on the width. So far it takes about 3-4 minutes to set it in place and it will run on 15 amps.

I just have to open the window, hang the stand on the window, push it in place, and plug it in. I am fine-tuning it to be mosquito proof for a trip to Minnesota in June.

It has high and low settings for cooling and air circulation and is fairly quiet. I could sleep with it running even though it would be just across from the bed.

As for cooling..... it claims to be able to cool 150 sq ft which is more than the Safari. I will see.......
Generally heat does not bother me much until it gets up over 100, so I think I won't have any complaints if it can only cool to 80 degrees.

I hope to have some photos and results to share soon.
Sam

Hi, I use a portable air conditioner to help cool part of my house. They are somewhat noisey, and like mentioned above, the hose gives off a lot of heat. This defeats some of the cooling action. I bought a collapsable A/C duct that has fiberglass insulation on the inside and aluminum looking material on the out side. I slip this cover over the exhaust hose, and tie it with strings on both ends. This stopped about 98% of the hose heat. One draw back is that this type of air conditioner will take up too much space in a trailer. A temperary window air/cond will work, but a roof air is the best way to go.

I have similar results from my portable air conditioner used in my house. It is a two hose unit, pulling in outside air to cool the condenser, then discharging it. I insulated the discharge hose using wrap around insulation from Lowes.

Nevertheless in my opinion it doesn't cool to its 14,000 BTU rating, more like 8-10,000 BTU.

The roof air is ideal packaging for a RV. The window air conditioners give more bang for the buck, and more real BTU per watt than the portable units.

I tried a portable and found it to be rather noisy, and took up way too much space.This is what I ended up doing.It's actually quieter than the roof unit, and 8,000 BTUs seems to be about just right for a 19 footer.

It doesn't really matter where you start your "whole project" thread...each time you post to it, it will pop to the top of the "Portal" or "New Posts" pages which are how most folks peruse the forums. I find it most logical to put it in the year/model section but others put their's in the various repair forums or elsewhere...regardless, each time you or someone else posts to it, it will display equally and garner the same traffic.

You could check these units out, they are made for big trucks. Click on Catologs then scroll down to 120-240 VAC units. I think these guys could put together anything you would need. Spendy though.

Thanks all. Portable Air-conditioner idea is squashed. Will do some version of the wall unit either in access panel or to be installed at campsite. I like the post from RideAir, your Safari is beautiful.

VIKING (Rich) did a floor mount of a low priced window unit that slides out and seals against the inside wall when in use then slides in and has a cover when not in use. I looked but could not find his photos. What a surprise, I seem to be 'search challenged" when it come to searching the forum.
