I ended up getting the Coleman regular profile 13500 BTU roof mount.  It was cheaper than the 9K BTU low profile unit so I figured I'd get the bigger one. Just have to order the gasket seal now.

Sounds like you have it well in hand, just be sure to have a safe back saving plan for getting that big heavy thang up on top of the trailer! Shade tree and a block and tackle should work.

Quick question on the electrical hookup.  Anybody installed a Colman-Mach A/C in their R Pod themselves?  I have it installed and in place but I have a question on wiring.  R Pod is prewired with Black (hot), White (neutral) and bare copper (ground).  The A/C comes wired with white, black and green wires along with a bare copper wire.  I know white goes with white and black goes with black but do I wire the existing bare copper wire to the bare copper wire on the A/C unit or does it get connected to the green wire?  From what I have read, you should wire bare to bare for the ground current if that's how the wiring is set up.  So does that mean I leave the green wire unconnected and capped?  I just want to make sure I am connecting everything properly.

Hmmm. The bare copper wire in the supply cable should go to the green pigtail of the a/c. The bare copper wire in the a/c might be there to provide a frame ground to the RV. Can you tell what it’s connected to? Any mention of it in the install manual?

The install manual is very vague. I’ll take some pics and post them.

See if you can trace where in the a/c the bare copper pigtail goes. I suspect it goes to metal, in which case you can attach it to the rpod frame and you'll be good to go.

I read through the manual and finally did find the detailed wiring section.  It was as you said.  Black to black, white to white and bare copper to green as you said offgrid.  Where on the frame should I attach that bare copper wire?

If the manual doesnt have a suggestion I think anywhere to metal that wont cause clearance problems would be ok. You could use a ring terminal to help with the clearance.
