Need info on adding 2nd A/C

I am considering adding a 2nd A/C unit to the bedroom area of my 91 34ft trailer. I have read on some older posts that a independent power cord is best to run the added unit. How do you run the power cord through the wall ? Do you have to remove inner sheet aluminum to do that ? Or what suggestions do you have. Thanks Davis

I ran the power and drain line forward thru the ceiling about 2' and into the bathroom. I removed the vanity mirror and exited the ceiling in the corner beside the vent stack tube, went down the corner behind the trim that hides the vent. I crossed behind the toilet and into the cabinet. The drain goes thru the floor while the power crosses back into the bedroom and is hidden behind some trim, into the street side nightstand where I added a new breaker panel. I added a 20amp plug thru the street side rear corner that feeds the new panel.

Clear as mud?

I will suggest using 3/8 copper for the drain thru the ceiling, a copper elbow to get the condensate turned down and out of the ceiling and then transition to hose. I first used hose in the ceiling and it would hump up, causing drips onto the bed.

Did you have to add any additional framing for the A/C ?

HiHo,
Is the wood framing used for supporting the weight of the A/C or to keep the inner and outer skins from compressing together ? Thanks Davis

I'm sure 10 people will give you 11 different answers...
In my opinion it has 2 purposes. By keeping adding a 'structural' member it keeps the inner and outer sections from pinching together by adding strength...

Huh?

Without the wood, pulling on either the inner OR the outer skin...no way to do a chin up...AND the AC unit would pinch them together...

WITH the wood, it's easy to do a chin up, well, possible for some people...OK I STRUGGLE DOING CHIN UPS!...but if I could, the wood keeps the ceiling from falling inward....
