When towing even light loads the LLY tends to run the fan under even slight loads or upgrades. I fabricated a couple of brackets and relocated my cooler below the boetie and now the fan only comes on under heavy towing or a steep upgrade and the cycle is much shorter and quieter. There are pics in my garage.:D

Lets move this to Allison OEM.

It's been done before; check out this link to my mod. Post #23 with pictures.

It's a heck of a good upgrade for a very small investment.

For the record,its BOWITE...not boetie.

Cool find and nice link to that other page,might be looking into that but might just go w/ the Mike L cooler instead as I need to pull the whole rig up to NJ in April.

your mod is nice...mine only cost $5.00 to do. And sorry for misspelling bowtie (bowite?)
