So I'm trying to find a good way to rid my suburban of underhood heat while towing. I know the Duramaxes have louvers on the rear of the hood and the 2011 louvers are supposed to be functional. So if it fits, hopefully it can help get some heat out.
If it doesn't directly swap, how hard is the front clip swap? Does it bolt right up or does it have to be modded?
I know this is kind of one off but putting it out there to see.
