Thanks, Rver. I have only vents in the air conditioner. Since I am in Bakersfield, CA, and it is 99 out I turned on the AC when I got plugged in and opened the vents.
With the vents open, the cold air comes directly down from the AC. I agree that it probably doesn't really cool anything off sooner, but it does cool off the living room faster, I think. I am going to close them now so the air will start going through the ceiling vents and reaching all parts of the coach.
Dawn, I agree with you 100% about loving living in my motorhome. It really feels like home to me, and I would rather stay here than anyplace else! I also am so glad to be rid of so much of my stuff, although someday I will have that 10x20' storage shed to deal with if I give this up and buy a condo or home again.
