My trailer has wiring to put a second A/C unit in the bedroom area where the roof vent is. I am pretty handy and this does sound like a complicated installation. I assume the unit will fit in the existing hole and I just need to wire it to the pre wire? I don't care about wiring it to the existing thermostat. Has anyone done this and can comment on complexity?
not that complex, you should look at the new units out there from dometic.. Use Eternabond instead of the dicor sealant. on the outside It's more expensive but you will never need to reapply it.
Biggest problem I faced was getting the air onto the roof. I used my tractor with a loader to raise it up and slide it onto the roof. Other than that, the rest was easy.
Really enjoy the air in the bedroom, but a word of caution is to not run both at the same time unless hooked to 50 Amp.

I don't know about the Eternabond, unless you think you will never need to remove the a/c unit. The a/c should have come with a rubber gasket to seal against the roof.
