get a factory mopar one from a junkyard, probably cost you less than 50 bucks. make sure its not rusty.
the factory mopar hitch is a class III/IV, and with it since you have the V8 you can tow up to 6500lbs (with a weight distributing hitch and all the other goodies). has a nice mount on it for a 7 way plug as well. another thing i like about the mopar hitch is that it tucks fairly tight up under the bumper, so there is less chance of it getting caught on something while off roading. when i bought my ZJ, it had a reese hitch on it, I swapped it out specifically because it hung so low (bottom of the reciever was a good 2-3 inches below the level of the gas tank skid)
Reliability is relative
