So my group tends to ride all day, and shiny blue cans may or may not come along with us. I have been looking for a cooler solution for the ride that would be big enough to keep a significant amount of drinks and ice but would be secured to the four wheeler without the use of bungee straps. This is something I came up with. I rode with this about 5 times now, and it keeps hanging on.

Cooler included, this was all probably about $40.

Needed parts:
2xturnbuckles (Lowes, $2.00 each)
2x ceiling flange (Lowes, $2.00 each)
2x threaded eyelets for ceiling flange (Lowes $4.00 each)
Miscellaneous nuts/bolts/washers to make it all come together.
Optional-rubber furniture stoppers for bottom of cooler ($5.00)

I have been looking for a cooler with strong enough tie down points and a locking top (other than strapping my real yeti up there). This is more or less a proof of concept, but the way it is working, I may just keep it the way it is.

The cooler I have does not have a locking top, so I run a bungee across the top. It seems to work quite well. The cooler does not slide, tip, rattle, etc. I was apprehensive at first, because the cooler has weak tie down points by the handle, but I have dogged it and it hasn’t broken yet.
