JMHO, but I think the Coleman Mach is a better unit. Why add a different brand?

I would probably prefer to add a matching Coleman unit; definitely not just sold on adding a Dometic AC, I just have not been able to find anything that comes close to the detailed instructions in this thread on how to connect a Coleman AC. If I could find any instructions on wiring up a Coleman AC like what is included here I would probably just go with that...

If itís in the front bedroom, I would probably just bypass all the hassles and put a ceiling control in. JMO, YMMV

FYI, I just heard back from ASA (maker of the iN-Command system) and they confirmed what I suspected (and hoped), that YES it should work fine with a different brand for the second unit as long as both can communicate properly with the iN-Command system. It will probably be about a month or so before I get around to installing the second unit; I'll update afterwards and let you know how it works!

When you do the project would you mind adding your experience and data to this thread so we have all the info in one place. Or, if you're supposed to start a new thread, would you post a note here that tells us to look for the new thread.

Thanks
Mike

Definitely! I think it should stay in this thread as I'll be using all the excellent information from this thread to do my project!

I just received all the parts this week, it may be a few weeks til itís installed but Iíll update then.

I donít expect it to raise it more than an inch, maybe two at most, as it is located next to the Winegard Air360 antenna which is fairly tall.

Any news yet on your install?

So sort of a non-update... I still have not installed the new unit, but I inspected the existing Coleman unit in the main (rear) part of the trailer, and it does not have the plug that was referred to in KC10Chief's original instructions, which is supposed to be connected when you install the second unit. There are several groups of wires that are connected with wire nuts, so I'm hoping that whatever function that plug served with a Dometic installation might already be connected in the Coleman installation. My plan is to go ahead and install the new Dometic in the front of the trailer using the rest of KC10Chief's instructions (along with the additional helpful info from Carlosgg87, markcee, and others), and see how it goes! Worst case, it will be a stand-alone unit with its own controls...

Curiosity makes me want to go look at mine. But survival instinct is telling me don't touch it if it's working fine. So, I don't know what the terminator plug looks like in the black box Bridge inside the AC unit, but I think in general it will look like the one pictured in the top right corner of this page out of the InCommand book.

Is this plug, the one with the black wire (or black shrink tube) the plug you said is missing? I think there's a resister shrunk wrapped inside there.

Did you get these pictures of KC's install? If not I can email them to you.

It's actually that bottom picture that you included. The plug on the right with the green and yellow wires is apparently hanging loose if you don't have a second AC unit installed, so you plug it in on your original unit when you add the second AC. Mine doesn't have that particular plug up there in the existing Coleman AC unit. Probably a difference in the gateways.

From my post #26.....

1. When looking at our existing gateway, we did not have the jumper connector that was to be removed and installed on the new gateway. Instead, we had a green/yellow wire with connector already in the slot. We left it intact. I'm am really glad we didn't have the jumper there to remove as there was about a 3" blob of sealant overflow that got on the gateway, essentially sealing the connector in place.

So ours was in fact plugged in already to the Dometic gateway, which confused us, as it wasn't 'hanging loose'. This does seem to be a difference in connectivity between the Dometic and Coleman systems and appears to confirms your reasoning.
