Thanks for the prompt reply! I have several vents on both units. Problem seems only in the rear vents above the bed. This just started so hopefully I can get the buggers. Not having owned a MH before I'm not ssure exactly how they're built.
When I look up into the vent I see Styrofoam? Also, I don't see any screws, are the louvered vents just snapped in?
I'm a pretty good mechanic so no worries about taking stuff apart! (With a little advise)
Thanks.
