So a buddy and I are going to build a shanty and we have a plan laid out taking designs and ideas from many of the shanties on this site. It will be T shaped with a 4'x8' foot print then kick out at seat height to an 8'x8' structure, we're doing it this way to accommodate the trailers we already have and or give it the possibility of fitting in a truck bed. Also that would make it fit in the path I cut with my wheelers (what we will tow it with) 60" snowplow. The one part we're not sure of is... Do you guys put one side of the roof on a hinge so it can be flipped open if the shanty somehow goes through while inside and and the door is blocked by ice or under water? or am I being way overly cautious? It's our first shanty build and would hate to leave out a safety feature everybody else builds into theirs just because we may have thought it was overkill.
