My deer hunt started with a BANG

Is that section of road marked as no parking/tow away zone?  If so, that would explain the quick tow without tagging and following the guidelines for roadside "abandoned vehicles." 

If not, when you picked-up the rig, the tow company should have given you a form to contest the impound/fees.  I would submit that within the time lines it says to contest it.
