I am also looking at getting a good cooler for my boat, I have all sizes of the Igloo up to 170, had the 200 qt but its too big to lift when full
I have 2 120 quart with the small lid on top, that will fit in my truck. I have a locking folding aluminum cover. So the height matters, but they do not keep ice frozen for more then a day, I believe the small lid opening (not insulated) causes this.

Does anyone have the Moeller 94 quart cooler. Saw it on Amazon for $255
