Light weight construction: aluminum “studs” in the walls and closed cell foam insulation are two construction elements I would absolutely demand as I’ve seen more than a few “stick built” houses that were warped and twisted all to heck after two years of use. Why does a 20 x 8 have to weight 3500+ pounds?
I’d want a light weight design that had the capability to be converted easily to skis out on the ice so I could easily tow it with a snowmobile or 4 wheeler. I want a permanent so I can stay out on the ice and be close to the fish. As soon as I have to stay close to my permanent because I can’t get it near the fish… the whole concept falls apart for me.
A house “drop” system that doesn’t rely on the “cable and winch” style system to lower the house. Sooner or later you’ll break the cable. Count on it.
This is the permanent that I think comes closest to being a “mobile-permanent.” http://www.customcottagesinc.com
