I got the 00395. And it looks like free shipping right now. Love it. Best $500 I ever spent on my 20 SF. I was doing the same thing you were doing with the cooler. The leaning post is night and day comfort wise. I'm a big fisherman too but I gladly sacrifice the deck space for a seat with a cushion any day
