In some embodiments, the self-propelled ice shelter includes a leveler attached to the frame for leveling the self-propelled ice shelter when stationary. The ice shelter includes a template attached to the frame, that is used to mark the position of openings with respect to the footprint of the housing that correspond with openings in the of the housing of the self-propelled ice shelter.
