On my 1999 I used to go to the hardware store and buy a small roll of window screen.  Each spring I would put in a new piece and remove it in the fall.  But while traveling pulling hard grades hauling heavy and hotter weather I have over heated a time or two.  Just would like to see what others have been doing with this issue also.

 So it does help with cab noise? And worth the effort and expense? 

 I ask because I've never used it. Never been one to have a booming stereo like that.

 I'd like to add that stuff inside once I get the rockers and floors free of the rust gremlins. Then the sound deadening and carpet.

It helped higher pitch noises, dampened it down, together with fte resonator works great.

Winter cover with little doors for keeping it warm in the cold, and a screen cover for those summer months for stopping the bugs. It doesn't fit perfect on 2001s, i questioned their measuring ability, but doesn't look horrible, and works just fine.
