I have an older Walrus Arc 3 (I think). Used on Rainier a couple of times. I am 6'1" and fit with room. It is a 3 man and not on the lighter end of things. It does have 2 vestibules though. Pretty sure it needs sealed again on the seams.
Here is a link with some reviews.

For $50 it is yours and I will cover shipping.
