I test drove a 2014 Silverado 2WT Regular Cab Long Box. We need a new truck a work since our previous 2003 Dodge Ram was a write off. Since we don't tow, don't need a crazy amount of payload, the 4.3 would be perfect since it will mostly be used around the city. Let me tell you, the 4.3 definitely has more than ample oomph. The interior was decent for a work truck. The truck drove nice, but the rear end did get unsettled over rougher pavement.
We ended up buying a 2013 Tundra SR5 regular cab long box with the 5.7L. Why? Well from a fuel economy stand point, it won't hurt us much more given we only put 10k kms a year on our truck. Second, over the same pavement, the truck felt way more settled and rode better than the 2014 Silverado. Third, the price. With current incentives and some negotiating, we got the truck for $30k even, all in, out the door. An equivalent Silverado would have been closer to $40k with taxes before any incentives ($1 - $2k). I don't think they would have considered knocking off $8k - $10k on this truck to get to close to Toyota's price.
