Tricky to describe, but I like to have a sealed transition from the outside through the belly skin, air space, insulation and then plywood floor. For my water heater intake a made a box like unit and sealed it up well. My goal is too keep water and debris from making its way into the area below the plywood or into the trailer. Really I guess any hole through the floor needs sealing and there seem to be many ways the skin this cat, and I'm always curious.

AC unit sets on a drip pan with drilled hole bottom of AC that lines up with a tube, tube runs thru the belly pan, tube is seal to drip pan with plenty of trempro 635. Also created a circular dam with the trempro. Hope this helps

Being 93 deg’s today decided to play around, tweeting, the AC. Was exhausting the heat back of license plate and what was happing was that the heat was transferring to the inside. Added a fan directly to back which eliminated that problem, air is now being circulated thru the back of license plate then thru the fan, metal on the inside is actual cooler. Will involve metal work, when opening the back door all you will see is a fan, when operating all I need to do is open the back door. Will add a variable speed switch to fan for dialing in. Temp in in trailer at 5:00 72 deg’s and falling.

The fan is made by Hayden, American made. Hayden - Electric Fans

Interesting plan; I got mine initially set up yesterday with just a 7" x 10" vent through the floor. I guess I was a bit hopeful but now I can see need something like your latest creation.

I'm thinking of a louvered vent on the wall just above the rear of the AC and if needed a fan like you've used. I'd really like to make mine idiot (myself) proof and don't want to have to remember to hit the fan on switch. Have you found one that cuts in at a certain temp at all?

Would a couple of these fans wired in series with the AC work? If the fans failed would the AC cut out too? I'd like to be able to leave the AC running without worrying about a failed fan and a melted trailer.

They're only tiny @ 4 3/4" but a couple should move 120CFM. Anything bigger and still 110V would be better.

Fresh air up through the floor (all ready cut hole 70 sq in); next I need (but really hate the idea) to cut a hole in the side wall. I have an old hatch I could use and prop it open or go with the louvers or flappy movable louvers. I guess I could cut another hole in the floor and build a duct to suck cool air up in one and blow it out and back from a second but that would really totally rely on the fan.

Decided to go with a second fan for the fridge, the 1/2” copper strap was bought at Lowes and bent to shape, the fan is a 3”, 33CFM, part number 273-243 from Radio Shack. Also added a on/off switch.

The attached link is the product I used on my fridge to greatly assist the cooling process. It comes with a temperature on/off switch. It's more of a air duct covering over the tubing that helps direct the air where needed.

Am I understanding this right that you are drawing air from the belly Pam and exhausting it out the side of the cabinet and into the interior of the trailer?
