I've been making 6 gallon batches in a Coleman 48qt cooler. There's plenty of room in there.
After a 6 hour brew day this weekend, I've decided that 6 gallon batches aren't cutting it. I need more! I'm buying a 17 gallon kettle this week, and I think the 48qt cooler is big enough for me (I batch sparge).
Anybody doing something similar? Any issues I might not be thinking of?
