This from Erik Haak:

This is an update to Dennis McGuire’s post from April 20th.  The vehicle that Dennis had photographed is no longer parked outside the building and now this was parked behind the fabrication shops when I drove past Sunday afternoon.  I don’t know which turret wagon this is, but its location behind the shops would seem to further the idea that the new rig will be some sort of deluge unit.
