NOTE:  The ThawRig's frame has been altered to mount the Vacuum Tank system for purposes of this demo ONLY.  The standard ThawRig does not include any such frame extension, since remote Alaskan gravel runways don’t require that runoff water be contained and the Vacuum Tank system is not needed.  For paved runways that require water containment, a skid-mounted configuration is recommended. 
See end of video for more information.
