As many have said, proper care goes a LONG ways. Get the hide off, then get any leftover hair, weeds, dust, and visceral material off then get the meat cooling and it'll be great.
Wrap it up in a blue tarp, strap it down onto the "yuppie-rack" plugged into the receiver hitch for a few days marinating the carcass in dust, diesel fumes, all while not allowing any moisture to escape and you might just as well find a dumpster for the whole works.
While this may sound sarcastic, I see carcasses on yuppie racks wrapped in tarps headed down the interstate every fall. Even when it's really cold the hide holds heat, the blue tarps hold moisture, neither keep out the dust nor exhaust fumes. BLECH!!!!!
