I'm full timing it, so I need to keep every single piece of hot air inside my coach as long as possible.........so I'm trying to insulate everything I can LOL.
I'm sitting in living are of my coach right now and count six (6) a/c "round" vents alone in the living area and kitchen. And no way to close them, i.e. no lever. So yeah, I guess they are designed that way for not necessary to close or cover. And same for the larger square vent I initially spoke of. And sure, one could cover using velcro and covering material, but all that would be unsightly. More importantly I guess, serving no purpose at all? For no Heat Loss thru any A/C vent, is that the bottom line?
