I finally, after way too much analysis brooding and reflection figured out a half decent way to mount a remote air cleaner.

My criteria was:
1. It had to be a real air cleaner, not a oiled washable one that in reality never gets washed or oiled
2. It had to be serviceable, changing the filter should not require disassembling anything or suffering too much
3. it must draw in clean fresh cool air
4. The filter must be readily available

I feel this install met all the above, #3 isn't optimal as the inlet is pointing down, but it's off to the side of the radiator and should be clean. I could possibly add ducting of I was so inclined
It uses a Wix 46573 filter out of a 2001 to 2020 Duramax. It has 190 square inches of surface area vs 110 for the stock filter.
This is the outside diameter NOT filter area.
Maybe Jim K can determine the actual filter area.
I used the Spectre hat and their 4" ducting, it worked out well. the jeep hat seems too small and restrictive for my comfort

Here is the bracket. This relocates the air tank closer to the fender allowing room for the filter

here is how the air tank and filter mount to the bracket

here they are mounted in the coach

Here they are from the hood side. the front cover comes off and the filter is 'easily' replaceable
