15025 is the 13.5k BTU unit non ducted
15027 is the 13.5k BTU unit ducted

15026 is the 15k BTU unit non ducted
15028 is the 15k BTU unit ducted

15021 is the non ducted ceiling assembly, includes flip down thermostat and IR remote
15022 is the ducted ceiling assembly with separate wall mounted thermostat and remote

Depending on the supplier the unit may or may not be listed with the corresponding ceiling assembly included. Read carefully.

These numbers are all for the white units. Also available in black.

A year ago I bought a Coleman !5,000 BTU unit on Ebay, was new and on the original pallet, I also had to buy a control panel for the inside.

The unit is noisy for sure and as I said at the GTG, it, I would think freeze me out with all that power, however it does just merely an adequate job of cooling my 25 footer.

Anyone feel the need to buy the Atwood 15KW unit? rather than the 13.5 KW one..?

I ought the 15K BTU, having only one unit in 28'.

It's plenty, but I should note that the worst heat for me is at star parties, where the windows have blackout curtains.

The front AC on the Monarch is an Atwood 15k (15026). I originally bought it to replace the single AC on the 33 Regal. I bought the Monarch before I got the install on the Regal done. The Atwood 15 is a heat pump system, is powerful, quiet and power efficient.

It is a great unit for the 37 Monarch. I have a ducted ceiling system, with just the 15k in front it is usually adequate.

I bought the 13.5K (15025) for the rear AC to serve as a backup.

Both of these units are billed as nonducted models but I have a ducted sytem, with inside ceiling panels I will keep using. For the first one I just removed the thermostat from the unneeded Atwood ceiling panel, extended the wires and mounted the thermostat on the wall. The furnace already has a separate thermostat so I didn't need 12v. (The previous Duo-Therm needed 12v.)

For the rear AC I bought the bare roof unit and thermostat only. I ran a wire to mount the thermostat on the wall. I like the idea of separate thermostats for reliability and better zone control.

IMHO I think it is best to have two roof AC's.
I had two on my 85 Barth MCC 35ft and most of the time ran them on the low setting, which kept an even temp thru the coach.
If you have any pets and leave them, even for a couple of hours, it's nice to know you have two AC's in case one decides to fail.
MY neighbor has an SOB and in the afterwards of hurricane Irma took his to a campground and left his two dogs in it while he cleaned up the yard at his house and did some repair work. When he went back later that afternoon the front AC had failed (he did not have the back one on) and found one of his dogs had died from heat exhaustion.

Just something to think about.
