Accidentally went under a low bridge and knocked my air conditioner out and replaced it with the exact same model although this one seems to be a more updated version. Because my last one was made in 2016 on a 2017 Flagstaff trailer. And if you've never done this before you'll need to know a few things. Number one, the circuit control board does not come with it that is a separate part. The pieces that are on the inside of the trailer, are also separate parts because there's numerous intake and exhaust methods used on different trailers for example this trailer is ducted, but that's part of the trailer design and not part of the AC unit so if you're replacing a unit that went bad, keep all those parts! Do yourself a favor and install a soft start as well.This unit can be bought for the cheapest here on amazon, especially when it's free shipping. The next best price is more than $100 more and it goes up from there.

Would have been 5 stars if the motherboard and freeze sensor had been included. Had to salvage these from old unit and thankfully they worked.

Like the fits just like the old one. Works well.Box was tore all a part. Unit was Lil bent. Better shipping would be a plus.

AC is drop in replacement and worked well after I fixed it. Arrived bent, dented, and coil fins crushed in. Luckily got it straightened out.
