That was the Freightliner that was owned by Mike Riggan of TanTara trucking based in Muscatine, Iowa. He now runs a Kenworth W900 with a different mural. TanTara Transportation Corp., Muscatine, Iowa
I have taken many pictures of both trucks at shows and by Kinnick.
That particular truck, Freightliner, is no longer used since Mike Riggan upgraded to the Kenworth with a different mural. The new truck has been in use for a few years now and can be seen with the different mural on this website. TanTara Transportation Corp., Muscatine, Iowa
