'Alternative' A/C - Will this work?

I have a 1960 18' Traveler which originally did not come with a roof a/c. Since I am trying to keep it as original as possible, I was trying to figure out a way to air condition it without putting in a roof air and, heaven forbid, a unit sticking out the window.

What I've come up with is this: Get a small window unit and install it in one of 3 places - under the bed (taking out a storage drawer), under the dinette bench or in the cabinet where the fridge is.

My plan was to construct a metal drip pan to go under the unit (with a drain hose) and a metal "air" box to go over it then vent the hot air and drip through a hole in the floor. I would have to cut a hole if I put it under the bed or bench but the fridge cabinet is already vented (it is the original propane fridge) through the roof and another screened hole in the floor.

Will this plan work? Would the back of the a/c be getting enough air circulation? Am I just asking for trouble cutting another hole in the floor? Or should I just find a small roof unit and run wiring to the ceiling vent? I only have 20 amps but could run a dedicated wire for the a/c.

Your problem is heat from the unit rises and has no where to go

I was thinking that the box that would go over the unit and vent through the floor would contain the heat and make it go out.

Yes or no?

I'm open to any and all suggestions.

If you did it your way, and I'm saying it is not a good idea, you would need a blower to remove the trapped heat from the box.

There was a post a long time ago about someone who mounted an AC to exhaust through a outside compartment space.

The thing that scars me about the idea is the possible proximity to the exhaust of any other gas system when your fresh air divider ( intake) is at the bottom of the trailer. Would you suck in any exhaust gas from any propane device at that location?

Read Uwe's thread as he did it several years ago and AFAIK is still pretty happy with it. It's a very long thread, but lots of good info in it.

I could probably use the portable one under the table or maybe in the bathroom (we don't have much spare space in the trailer) and somehow figure out how to vent the hose. Do I need 13000 BTU or would 8,000 BTU be big enough? The interior is about 16' x 7' with most of that space taken up with bed, dinette and cabinets.

That is really up to you. They won't cool as much as they say on the box - I have one-

I posted lowes because if it is too big or too small you can return it or swap it without a lot of hassle

They are slightly louder than a window unit but it makes for some good sleeping

All you need to do is find a path for the 5" hose to exit your trailer

I'd want to go with the portable room AC.
Path of least resistance.

When you first plug it in give it half a day before you judge it .

It will have to remove all the accumulated moisture in your trailer before it will fell super cool

Thanks for the thread - I've been checking it out and that split system looks perfect - although it IS a bit pricey. Now I've got to decide what to do...
