I don't know why, but quite often only the body is available on Ebay. I once found a Humm Vee on Ebay that didn't run, had no battery, charger or controller, for $100 PLUS $30.00 shipping. I emailed him and told him I already had purchased one BRAND NEW for $125 and would give him $60 shipped...
I just did a little looking and sure enough, New Bright makes one. Not sure what year this one is but it has to be pretty close. This is at Overstock.com but they are currently out of stock...
I moved it where it will get the attention it deserves. Good luck with it.
You might want to see if New Bright or Nikko has a version of that truck. I have 3 of their Humm Vees that I've turned into fully detailed military vehicles using ONLY the body shells. They are toys in the world of RC...
