I concur with the OTR A/C as our liberty is so equipped. Cool as a cucumber going down the super slab! Only draw backs are it does affect your MPG slightly,it is rather noisy when parked with the RPM elevated and if you happen to hit a patch of road that is unpaved it creates an enormous cloud of dust. We have an unpaved portion of road leading up to our getaway property and we shut off the OTR for the last mile to to avoid a dust storm. Aside from that you learn to live with the tiny draw backs. The loss of primarily 2 bays is not even worth mentioning in our situation.
