We have this problem with our motorhome and I know it is pretty common. Just viewed a website advertised in FMC magazine for a "fix" (foggeddoublepanewindow.com). Has anyone bought this manual ($32) and performed the fix? Does it actually work? The ad makes it sound easy -- is it? How much additional you do have to invest in parts, etc. to implement the fix? Would appreciate some feedback. Thanks.
