I don't own one, but i'm a fan of Frabil. They make god quality stuff. Check out some youtube videos that should give you perspective of what they're like. I wouldn't buy one unless you're towing it with something though. Definitely too heavy to drag as you walk in any depth of snow.
There is also a youtuber named "OB Outdoors" and i believe he fishes out of a Predator. Has plenty of room and fits all his gear and there too.
