Coleman Mach 8

[KH325BHQS]

I need to add a 2nd ac to the bedroom of our rig, I am looking at the mach 8, for those of you who have this , how is the performance for the 13.5K or 15K?Also how is the noise level on low and high ? Thanks, for the replies in advance.

We have the factory installed 2nd A/C which is the Mach 8 13.5K
The Mach 8 cools the bedroom nice and on very hot days we run both A/C units to help cool the trailer down.
If you have 50A service you'll be able to run both units, but if you only have 30A service, you'll only be able to run one A/C unit at a time.

Biggest complaint of the Mach 8 is that it was extremely load, sounded like a jet engine taking off.
I contacted Coleman-Mach about the noise and they sent me a Mach 8 Hush Kit.
Once I installed the Hush Kit, it reduced the noise significantly, but it is still load. The Hush Kit included a new fan. But for us, it's still too load to run at night when we're sleeping.

Our trailer is a 2015, built in 2014, so not sure if they've made any changes to them.
I see Jayco is now offering a low-profile 15K as the optional front A/C unit.

You can also look at the Dometic Penguin as another A/C unit to consider. I've heard good reviews on this A/C unit.

Hope this is of some help.
Good luck.

We have a 13.5K Mach 8 in our HTT. it has more than enough power for our hybrid. It is loud, but we sleep right through it.

X2. We run a sound machine for sleeping anyway. This unit eliminates the need for the sound machine. Plus I have blacked out all the windows in the bedroom so I actually sleep much better in my Eagle 5th wheel than I do at home!

We have the mach 8 in the main living area. I think its a little louder than the 13.5 btu unit we put in the main bedroom. But neither are bothering us in regards to noise level. We added the second unit this past summer and if my memory is correct I think they said it was the Mach 10 low profile model. The good news is we haven't had problems cooling the place so far. And we have the 375 BHFS so it's pretty roomy.
