People ragging on Ice Castle quality reminds me of that old Yogi Berra quote: “Nobody goes there anymore. It’s too crowded”.
With the amount of Ice Castles you see on the road at all times of the year now, you’d better trust that people are happy with them. It’s like people who refuse to buy a domestic Chevy or Ford because they one they had in 1999 was a junker. Yeah, and those car makes are at or exceed the quality of the foreign auto makers now.
The other thing that think about is that RVs in general are far from flawless. They are thrown together very quickly in an assembly line setting.
