I have my doubts wether the single Rhino is going to make it anywhere far since people know what badassness is in it. I know it'll really shake up your 1500 point list but I think you need to work in the LRC you have pegged for 2000. Personally, because of the one turn delay before charging, I think Purifiers in Rhinos or Razorbacks is just too much potential lost.

Any suggestions on what to sub out for the LRC?
