Thank you EVERYONE for the input. I don't think a single 15k will be enough. I was really hoping the "prewire" would have been up front in living room. The bedroom is quite comfortable.
@ Irish2: Its been around the 90 degree mark. I see a 2nd A/C in my future...
@ AZCL: Will definitely crack open the roof vent up in livingroom.
@ Bumpyroad: Agreed. I think I'll put the smaller one in the back.
@ bqcooker: Love it. 10,500 empty. Fully loaded, we're somewhere around 12 or 12.5k (all our gear included) Powerstroke doesn't even know its there. About 1700 RPM at 65 MPH.
@ Lee Worsdell: Doing the fan thing now. Hoping to bring overall temp down without turning bedroom into walk in fridge.
@ Coach-Man: Not sure how to do that inside? Its a "whisper quiet". Nothing inside except 2 intakes on either side of kitchen.
@ Taking the 5th: Definitely! Thinking about adding a ceiling fan up front.
@ Mandalay Parr: Sounds like the way to go.
@ScottG: I'm finding out quickly that more is better! lol
Again, Thanks everyone!
