Has anyone had to replace their AC and if so what did you replace it with? Looks like I had the Dometic 15K. It blows no cold air at all as we found out a few weeks ago when it was 105. While its not a big deal at this point in the year, I'll need to replace it before March for a planned trip to AZ. Looks like a pretty easy job since it looks like a plug and play deal. Maybe one of these days I'll get a trip in without discovering yet another issue...
