I bought a 150qt Marine cooler a little over 2 years ago. At the time, it was very empty and I thought "I'll never run out of room"
It got to the point where it was difficult to keep moving boxes all the time so I got the drawers and shelves from Forrest and thought "finally, I'll have the room I need".
Now I'm considering a secondary, long term storage cooler.
I realize the shelves aren't stuffed, but they full enough it's hard to move stuff around.
Both drawers I've had to double stack to fit all the singles.
Moral of the story....always go bigger than you ever thought you could possibly fill.
