    • Highly, extremely disappointed!

When opening the box, and the unit unpacked, it showed extremely poor workmanship. Bent supporting structures - not diminishing functionality. A sealing plug was not in place - I put it back as best as possible, cutting my hand on the sheet metal. After installation, the unit runs well, but during the night forms condensation on the ceiling unit, and now I found is leaking condensation through the roof lining, which will cause severe damage! The unit works, but is of very low quality and workmanship. NOT WORTH THE MONEY I PAID FOR IT, AND IT REALLY SHOULD BE REPLACED WITH A UNIT IF BETTER QUALITY! ... show more

    • Easy to install!
Took my friend and I about 2 hours to install (which includes the equipment inside the RV. Nothing difficult other than lifting it up to the RV roof and running a new wire through the RV (since mine was not pre-installed. Running this wire took about 6 hours.) As to noise level... well, you're installing a non-ducted air conditioner about 4 feet from your sleeping head. You will hear it. ... show more

So far it is performing well for an A/C in an RV. They can only do so much in 98⁰ weather, especially if cooking with gas indoors!! Would definitely recommend it if you are considering replacing yours.

    • Nice cold air
Everyone was right. Getting it on top of RV is the hardest part. Hook up easy and instructions good. Cover or shroud does seem a bit flimsy.

Unit works but was not how you expect a brand new Unit to look. Bottom all bent up, fins bent. Expected better condition. Box not damaged so packers knew condition. If we didn't need it right away we would have sent back & not tried it Disappointed
