I need to tow my jeep cherokee behind my truck is there a simple way to provide a 2" ball to do this?

How far are you going? 1 way or round trip?

How will that matter??? One way most likely. About 300 miles

By the time you wire up (if needed) and buy a hitch you may find it easier and/or cheaper to have it transported to destination. If it was going 2000 miles and you needed to bring it back, transport might not be the best option.

Look at the picture in my avatar. I saw a guy using vice grips to hold a trailer hitch to his truck one day.
