Cool Air Again for our Small Camping Trailer!

Our old Zenith AC in our 2011 Aliner camper died on our last trip. It took us several hours of research on several days to find one that would fit in the place cut out in the side wall that the old one came out of. This LG model was almost perfect! My husband did a few mods like cutting the "feet" off of it and was able to use the old metal bracket to set it back up in the same place. A little caulking and drilling some extra holes for rivets and the unit fit right in the space. Controls and vents above the cabinet and the inside cabinet is still useful for supplies. We couldn't have chosen better! Cold air was down to 65 within 30 minutes after we set the temperature where we wanted it. It also has movable vents, remote control and temperature window. Good cool air, reasonable fan noise, price and shipping. We are thrilled with our easier than we thought installation!

Didn't really get to use this unit but a couple of weeks before having to turn it off because the weather changed. I like the remote, as it's hard to get to the unit in my room. I don't like the vents, they blow up and I prefer for them to blow out into the room, from the front of the unit.

Works as advertised.

Cools down our bedroom quickly. It does have a bit of a thud when the cooling turns on and off. It's not terrible, but worth noting The fan noise is average, the display is bright but can be shut off if desired. All and all it's a decent air conditioner for the price. I would buy again.
