Another ac window unit thread

A blob of polyurethane caulk will keep it from vibrating too much. Polyurethane, not silicone... not butyl rubber... not latex...

 

You do not want deep cycle batteries for that application at all.
On your regular truck air unit, is both fan motors working? It is pretty hard to tell unless you remove the seat and visually check, and if it is like my 97, only one comes on until you put the fan on high.
The way the ducting on these is set up sucks, and I have always thought a guy could do some insulating and improve the factory air a lot.

 

There are dual use batteries that are cranking and have deep cycle abilities. Ask your dealer I got them at my freightliner dealer. Charge ALL your batteries full and have them load tested. If they all don't pass. Replace them all with the same batteries. Disimilar batteries joined together does not work well, as having one bad one.

 

little update. still have the broken ac in my truck. gonna pull it out and try a stand up ac if i find one with low enough btu and that will fit between my seat. think if its on the floor and not the wall it should vibrate waaay less.

now to find one that will work with my 3000 watt 6000 peak watt inverter

 

The one I had a long time ago o my used 350 watts. I think the surge to actually kick it on was 800.

That was 15 years ago but I can't imagine they've gotten power hungry since then.

 

ya i overshot the inverter so i made sure it was gonna handle the startup watts. problem im finding is these standups are limited for the 5000 btu like my little wall one. most of the smallest ones at the local stores are 8000 btu and dont list the watts on the box.

 

also they show 2 ratings. one i found says 8000btu ashre and 5000 btu doe. dont know which to use to figure out the watts lol

 

That’s the problem I ran into. Have an 800 watt, I ran it on a 2000 Chinese Honda knockoff. It worked, occasionally tripped the breaker. But the portables draw more amps, per BTUs. I think they’re a waste of money. Barely kept the bunk or the Cab, cool during the day. Worked good at night, though. You should really consider a mini split. There’s a great thread on here. One mini split set up, seems to be the best I’ve seen yet. Not much more than a portable.

 

true...but i would be worried about the vibration again cracking the lines. would be harder to keep toying around. think a stand up unit would have much less vibration. i just cant find a 5000 btu one like my little window unit

 

That’s the problem, smallest I could find was a 800 btu, single hose, it pulled as many amps as a larger btu window unit, it was a waste of money
