The Coleman Mach 8 comes back at a good price...but it is good for a 30ft AS? Do I really need a 15K?? Keep in mind I live in SOFLO and the summers are brutal.
Thanks

A better option...

Last year the Dometic Penguin low profile AC on my 2011 FC20 stopped cooling. I spent a lot of time researching a replacement, and decided on the Atwood Air Command instead.

Here's why:

It's lighter than the Dometic.

It's about 4db quieter than the Dometic.

It comes with a remote control - can be adjusted from bed.

It has a dehumidifier setting, which I've found very useful.

It costs less than the Dometic.

...and the biggest selling point?

It's so efficient that it can operate on ONE Honda 2000 generator. I've tried it, and it works. They even have a photo of the Honda generator in their brochure.

There are downsides...

The unit is taller than the stock dometic. A photo of my rig with the Atwood is attached.

Only the more powerful unit (that cannot run on a single Honda 2000) features a heat pump.

You will need to get a new thermostat - but only for your furnace. The Atwood has a control panel on it + the remote. It's a little more complicated than it sounds, in that my old AC was wired directly to the furnace. A digital connection ran to the wall thermostat, so a new (heavier gauge) wire had to be pulled from the AC mount to the wall thermostat. The AS dealer here in Chicago had no problems doing the job, though.

Here's a link for more info. I've no ties to Atwood, other than as a happy customer.

Atwood RV Air Conditioners
I'm not disparaging your choice of Atwood in any way, but I have to inject my last 10 years of experience dealing with them on a professional level:

• their products are unnecessarily 'over' engineered (this is coming from one with a Master's degree in engineering) which makes repairs more difficult than they should be
• their warranty service is extremely stingy and their repair reimbursement process sucks!
• they are very fond of stating how their products perform at higher 'equivalent levels' than their competition when in fact, they play little tricks to say that…. EG: their water heaters run at hotter temperatures and require an external
'tempering valve' to mix cold water with the tank water to get 120ºF at the faucet. They never discuss the required cleaning of said valve, necessitating costly replacement every few years.

These are real world observations and experiences from a professional view point over many repair/replacement episodes. I NEVER suggest any of their products due to the above!!! YMMV!!

Yeah, I didn't mention that in my post, and don't believe in any rating that has the word "equivalent" next to it.

That said, the AC unit is definitely quieter than the Dometic, and it cools the camper very quickly. The warranty is 2 years - but the second is only for parts, which is pretty much worthless because neither the Atwood nor the Dometic units are repairable anyhow.

So I'm happy, but keeping my fingers crossed for reliability - both brands have the same warranty, and my Dometic only lasted for 4 seasons of use, which was a disappointment.

My wife really disliked the loudness of the old AC, but doesn't mind this one, so the reduced air noise is substantial.

Happy Camping!

Glenn

Not true!

There are several parts that are replaceable and have been replaced under Dometic's warranty (which BTW, is a 2 year full parts and labor with an extended available for year 3 and 4).

Items like blower motors, control boards and solenoid valve coils for heat pumps are replacable. The most common warranty claim is for a leak in the refrigerant system, which then requires unit replacement, but you get stuck with the labor in the second year with an Atwood, where it is included with Dometic or RVP/Coleman.

Geez - these new units are really not field repairable, are they? I just repaired a refrigerant leak in my old Armstrong, and now it's working fine.

A professional would have taken a couple hours, including pulling the vacuum and recharging. I ain't gonna tell you how long it took me!

There hasn't been a 'field repairable' RV air conditioner since the Armstrongs.
