Has anyone notice that we ahve vents on the wall behind the cabin.WTF are they for besides letting in cold air.:cuss:
If you're thinking of covering them or blocking them (with sound deadening material for example) - don't. One of the times they really help is if you're in an acident and the airbags deploy. The air has to go somewhere when those bags deploy, and the vents allow for that. If they're covered, I hear the next weakest thing in the cab for pressure is a person's eardrums...
