182G New A/C Install

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.

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. 

A 9000 btu minisplit is whisper quiet inside and out and has no ductwork. So it is very possible. The problem is that RV owners and manufacturers have not insisted on improvement from Dometic and the other roof a/c manufacturers.

Cheaper always gets my vote too unless there is a compelling reason to spend more hard earned $$$.

I don't know if it is or not. Its not really going to produce noticeably less air drag so if it has the same btu rating its going to be a matter of noise level and aesthetics. The standard 13.5K units are almost unbelievably noisy so it might be worth doing some checking on noise levels and basing your decision on that.
