Have Geo tracker with 235/15 mud tires. Will go most anywhere a utv will but makes deeper ruts. The deep ruts is the part I don't like about it. Never had it stuck yet and do have some swampy pastures that am real careful about. 

It's my street legal, warm and dry utv! Would think a S10, Ranger or Tacoma small truck with big mud tires would work well also. Does anyone have one of those for utv use?
