Outbehindthebarn Posted October 3, 2016 Share Posted October 3, 2016 What did Mack use in the back of the cab on R models. My Superliner has the big diamond pleated back panel the surrounds the rear window and goes to the floor, but there is nothing between it and the back panel of the cab. Seems like a pretty big waste of space really.... should I just fill that area up with insulation? Did Mack have some sort of 'fitted' insulation panel that went there? Secondly, what is the large metal kinda pyramid shape thing standing up there? It is welded in place near the rear cab mount and almost reaches the rear window opening? Does it serve some purpose? (sorry for no pic of it) Quote Fun is what they fine you for!My name is Bob Buckman sir,. . . and I hate truckers.

Coenut Posted October 3, 2016 Share Posted October 3, 2016 I don't think there was any insulation in my cab either. I plan on using a dynamat product. The diamond shaped panel I'm pretty sure secures the mail pouch.

With that big void under the window, I suppose it needed a support of some kind. Quote Fun is what they fine you for!My name is Bob Buckman sir,. . . and I hate truckers.
