Well........after trial and error.........It does fit.....But I had to remove the top of the cooler compartment! However, very disappointing! My Boat has Marine A/C builtin. Even with that it didn't refrigerate well enough to do the job! It advertises that it cools 40 degrees between the temp outside and inside. That should have kept the food between 35F and 40F. It didn't come close to that. Milk spoiled, Steaks went south, cheese was soft.....and more. Final answer is.......DON'T DO IT!! Hope this will help another person considering the change. Thanks so much for all the input and conversation. I wish everyone well!!
