I used a Ram 1500 with the 3.6 for a few weeks hunting in Wyoming a few years back and was impressed with how well it worked in a full size truck. Plenty of power and very good economy. My brother has a Jeep with the 3.6 that he's driven from Florida to CA and back several times and he's a huge fan...gets great MPG for being a Jeep truck and so far, zero issues. Neither of us tows, but we're tough on trucks generally.
