I opted for the 4.7 L. V-8. The power is tremendous. All the big truck qualities in a mid-size truck. Very comfortable ride. It will tow 7000 lbs. Gas mileage is the only downfall for the 4.7. Overall, the best vehicle I have ever purchased. Kudos to Glendale Dodge in California. No hassle, no haggle, no grinding. Just sold me the truck for the price I wanted.
