Trekr200/Mike there is limited activity on Ice Shanty at this time of year. Look through the Ice Shack Tips community/forum there are many photos of various types of shanties/bob houses . Some of these threads follow a members' build from start to finish. I believe the bob houses on Ice Holes have wheels and may drop down to the ice surface or have some type of tubes running from the floor of shanty to ice surface for each hole. These type of shanties are built on trailer frames or are converted travel trailers/campers. When you search through the Ice Shack Tips forum like for a thread started by Da Man Cave Shack ,he built a high end shanty from an old trailer /camper frame. This shanty is finished like Josh's on Ice Holes.
