One of the downfalls to towing with a unibody vehicle is that the noise from the trailer is amplified throughout the cab. Thanks to the sound-deadening of the Grand Cherokee, this wasn't a huge issue. The only time it was a problem was on the deadhead portion of the trip from Los Angeles to Ohio. The unloaded trailer bouncing all over the place really rattled the hitch and could be heard in the cab. This $20 item from the local trailer shop silenced it nicely.
