I just got back from a 4000+ mile round trip to Moab and back towing my Fleetwood Evolution E3. (Not without incident, see my posts on bad gas). The dry weight of the E3 is 2900 and is pushing the 3500lb limit when loaded up with camping gear. The JK did ok, it wasn't a barn burner by any stretch, and the boost gauge was in the 2lb boost range for most of the trip (could be why, in combination with the bad gas, the one spark plug failed). I'm just glad I had the supercharger. I also tow in third (1:1) gear.
So, the JK did fine (with a few exceptions) with the supercharged V6. All in all, I wish I had a V8, especially in that long climb out of Denver on the way up to the 10000 ft level. There I had one stretch following a semi at 25-30mph in first gear. There was no way I was going to pass him (I could have slowly gone around him at the ire of all the drivers passing me at 65mph+)
