One of the "knowns" with the "Budget Birch" was that the roof AC unit was disclosed as dead by the PO (who got that info from the previous PO).

I opened it up this week and the air circulation fan does not move freely when the fan is turned by hand and one of the ac feed wires had melted the wire nut where it connected to the controls. I repaired the wire, but have not hooked up to shore power to test, but I am not hopeful - the unit is old and the fried wire was likely caused by the stiff fan motor.

So I have been looking at replacement options. The penny pincher in me says buy the cheapest new replacement unit available and motor on. The old man in me says buy the slickest, high capacity unit money can buy because you don't want to do this twice.

Also, because everything on this little escapade has cost twice what I thought it would, I am starting to get acutely aware of need vs want.

So, What size unit? 13.5, 15?

The low profile units are nice, but is 4" height difference on a 9' high coach really worth the extra dough? In the case of available 13.5k units, the price is double.

I'd love to be able to get an AC unit that would work on a smaller generator, but I don't want to sacrifice cooling power, and in the humid south the task is formidable. I want to have a walk in cooler when camping in August.

What size/model unit are you fellow southerners running in your 23' coaches, and does it do the job? Obviously, if the coach has additional insulation it will boost the performance, so please mention if the coach has been so equipped.

Any nuggets of wisdom on the topic are appreciated.
