i need to put a hitch on my new van, it's a diesel . i could go with a 2" 10,000 lbs, or 2.5" 12,000 lbs hitch. obviously the 2.5" is a little more odd. is it easy to find accessories for the 2.5"? do they make reducers, incase i need to use a 2" accessory? or should i just get a 2" hitch? i'll be pulling a big skid loader.
