Not sure about this, but I will pass on what I was told by the previous owner of my 20023t. He said the boat came with a "factory" cooler. It is nothing more than a Coleman cooler that fits in a shallow tray mounted in the rear portside compartment. The cooler itself has model #s 5281, 5282, & 5283 molded in the bottom. I assume the different #s would refer to different colors. I would expect the tray would have been an Allison part, but that is speculation on my part. Will be happy to supply some pics if you wish.
