Which a/c for 18' trailer

I do want the trailer to get cold, but not too cold and not too loud. The contenders so far:

1) Penguin 11K BTU
2) Penguin 13.5K BTU
3) Coleman Polar Cub 8K BTU

My impression is that on an 18' trailer, the 8K will provice enough cooling power. I prefer the appearance of the Penguin, the coleman is not so good looking IMO. Penguin seems to be a popular and good looking choice for vintage trailers (as I've seen on the forum). Cost is an issue, and CW stocks the 13.5K unit for a very competitive price.

The concern is choosing the right AC. After spending a bunch of money, getting it up there, glueing it on, plugging it in -- Will we need to wear ear plugs and cover up with a blankey?

Have you experienced how loud these units are compared to each other? The two penguins appear to share most of the same parts except for the compressor. Does the 13.5K seem bigger from the inside of the trailer -- louder and more vibration?

Somewhat attached to this question is heat pump no heat pump. The trailer has a very burly 11K BTU wall furnace that is either on or off. I would like a heat source with a thermostat. Being able to use the heat pump for heat may be a good choice for this trailer.

Your thoughts on this are appreciated, I'd like to do this project once.

Ryan.

No Glue!!!!!!!!!!!!!!!!!!!!!!!!!!

Ryan,

I have an '06 19CCD with the Penguin 11K and it will get the trailer to meat locker temps! I'm not sure that the 8K would do the same. The exterior and interior dimensions are the same for the Dometic units, the only difference being the compressor size and the amount of coil area.

You can probably add a t/stat to your furnace without too much trouble. All it does is act as a mechanical switch to turn the furnace on-off at the pre-set temp.

NEVER GLUE AN A/C UNIT TO A ROOF!!!!!!!!!!!!!!!!!!!!

There is a gasket on the bottom of the unit that is compressed to 50% by 4 bolts that hold the unit to the roof. you also might want to inquire about a drip pan from Dometic that will better fit the curvature of the roof.

Have fun with your install

I too had a 19' Bambi with an 11k unit w/ heat strip. I found that it did an good job as long as I was not in direct sunlight. When in direct sunlight it seemed to struggle. I think that a 13.5k unit would meet and exceed the need. When I upgraded to a 25' unit, the base A/C was again 11k, upgraded to 13.5k as part of the LS package, but I instead opted to take it a step further with a 15k unit since the 25' Classics had it as an option and based on my exp with our 11k unit in our 19'.

I've been very pleased with that decision since the first summer season I used it. In your case, though the 11k unit would work under some or most situations, I tend to hit a fly with a sledgehammer and put in a bit more than I need to cover as many more situations as I may encounter. If I were in your shoes, my plan/path would be the 13.5k unit. I've had some great exp with the Penguin units and they are low profile.

I second the Penquin with a drip pan. You can get the drip pan only for for the Penquin from Airstream. It fits under the AC and has a cavity that collects the condensate from the coils and dumps it into a tube running thru the wall. Since ACs weren't factory installed until later I think you will have to run the drip line also. I just did this for my 63 Globetrotter. I have the 13.5 Penquin and it is plenty cold. I went to this trouble because the condensate stains a polished Airstream.

As far as noise, the fan does generate good white noise. It masks outside noise during the night. I can also hear the compressor cut in and out but its not disturbing.

Thanks for the info, and so fast!

Lew, no glue, noted. I'd like to hear more about adding a thermostat to the Glen-Aire furnace. I don't like the idea of having the pilot light lit when we sleep, it keeps my son awake. Plus,the large size of the burner and huge flame it makes makes me not trust it unless I'm sitting next to it, awake. I've called around to some of the old time RV paces in town as well as propane parts houses and nobody has ever heard of my setup. I'd like to have the whole thing bench tested and a thermostat added if possible.

Jbond's photos shows the curvature of the drip pan. It looks great that close to the top. Is my Airstream dealer the only place to order that part? I haven't gotten a warm reception, people there seem to take turns not knowing what I'm talking about. (last time I stopped in there looking for small tester jars of Nuvite. I shoud have known better)

I will be adding a drain tube, I'm pretty excited about this. My parents motorhome drains down the side. Maybe their draintube is clogged. Plan is to travel down the curbside wall as far as possible, come through the skin into the wardrobe closet. The power will go to the pushmatic breaker panel, the drain tube will go through the floor and bellypan, and on to the ground.

Ryan.

Getting ready for the install

So I have the Penguin 13.5K new in box and the drip pan from an A/S dealer. I've got a few questions before I tackle the install.

I spent some time on the phone with the A/S dealer service manager (good guy) on the procedure they use while installing this setup. It conflicts with what I've read here. Procedure they use:

-remove neoprene seal and foam blocks on air conditioner from factory.

-apply double stick tape around perimeter of drip pan. Place A/C on top of drip pan. Taped together, A/C is ready to be placed on trailer top.

-Apply Vulkem to top of trailer around 14 x 14 hole. More Vulkem is applied to top of trailer where drip pan touches down.

-Follow the rest of the instructions included with A/C.



How does your experience differ? I was told here not to use glue on the installation, which seems to be good advice. What should my plan of action be? Here's what my plan is so far.

-Leave neoprene seal on A/C, remove foam blocks so A/C will fit tight to drip pan.

-buy A/C seal and attach to bottom of drip pan.

-place drip pan on top of trailer

-get help to lift A/C into place on drip pan, already on trailer.

-bolt down and follow rest of instrucions supplied.



Sound right? Help please!

Ryan.

Ryan,

I tried this method and it worked very well.

1. While still on the ground, dry fit the neoprene gasket between the A/C and the drip pan. I found that the gasket interferes with the drain channels, so I used a coping saw to remove part of the gasket where the interference was. You can see the area I cut out in the photo below. This lets condensate flow more freely to the drain tube.

2. I mounted the pan first. Held it down with putty strips around the roof opening and the perimeter of the pan.

Putty strips like Plumbers Putty? That is what makes the seal between the drip pan and roof of trailer? Will that work over the years to keep rainwater out of the trailer while on the road?

I noticed that is what Dometic used on the inside of the A/C to make electrical wires more windproof as they pass through holes.

Ryan,

Ryan RV product called 'butyl tape'. It's used to seal a lot of items on many types of RVs, and it's stickey to!

Aaah, butyl tape. I see that here in my 'toy' catalog.

Thanks!

Should you ever travel to southern California, or other hot spots, you will wish you had a 15,000 BTU AC.

Granted where you live, a smaller unit is ok. But, someday you may wish to travel to a hot spot.

The difference in cost is not that much between a 13,500 and a 15,000 BTU AC. An 8000 is absolutely not enough when the sun hits the shell.

We would suggest that you consider the 15,000 BTU AC, which will cover "all" of your bases, not just some.

Andy
