i've had an ice castle and a zack shack, along with a few home made ones...
the ice castle was great to party in, and more comfortable, but a pain to move... that part comes from EVERYTHING you can fit in it that has nothing to do with fishing (my fault)... mine became more of a camper on ice...
the zack shack was great for fishing and moving multiple times per day chasing fish... yetti is basically the aluminum version of the zack shack, and will be easily moved with minimal snow by a 4 wheeler...
only drawbacks of the yetti MIGHT be the softer metal, and a mechanical axle system dependent on a winch, but that would be it... the major PLUS would be that your season is extended both early and late...
