What do YOU need with a dually? That just makes more parts to replace when you throw the tread off your tire. Remember Bill's tireless (no pun intended) search for some fenders? Found some 50mi from me. Plus, there are 2 extra tires back there. BTW- I dont "need" one, either, but for the price I paid, it was a package deal. 3-figure pricing- buyer cant be choosy.
Is the dually in question a slushbox or stick?
