As stated on the Mr. Obvious show......Long time listener first time caller. So the big question is, what is the purpose of this removable rectangle, with nut, on the back of my cab? I have tried searching and have looked in my FSM but can't come up with what the heck its for or its purpose. Any idea? Thanks!!

 

Its a vent I allows you to shut the doors, IE there would be excess pressure if it wasn't there.

 

Thanks alot hunter4runner!!! Its been rattling my brain for days trying to figure out what the heck its for. Thanks again!!

 

You guys! Does at least one of you know that hunter4runner is pulling your leg?

I have no idea what the panel it is for, but I know that the heat/ventilate system is not airtight. You can close the doors without any extra venting.

 

HAHA well it made sence... I know there is a breathable type grommet on each lower side of the back of the cab by the rocker panels. I was baffled because this rectangle piece has seam sealed on the upper half. Inside the cab it has a black round sticker that looks like it seals the hole, behind the nut that is visable outside the cab. I thought it could be used as a cool antenna mound if you could put a swivel on the nut to raise the antenna or lower it to be hidden between the cab and bed.

 

it's actually a "tooling point" for production of the cab


.

 

My guess is either something necessary for production OR for specialized applications where cabling or hoses could pass thru to the rear like for farm implements or things like that used in foreign markets or local government uses.... Not that Ive ever seen anything like that.
