I could be wrong, but doesn't the 6.2 require Premium Gas vs 87? That was kind of my reason for the 5.3L choice. I like my 5.3 plus with that 10 speed transmission makes up for having a 3.23 rear gear. I was use to a 3.92 in my old RAM but I feel it has plenty of pep in comparison with my old RAM's 5.7L. If the economy was in a better way, I would have gone for the 6.2. But we are living in uncertain times. Go with what you can afford. If you can swing it, get a 6.2 with the LT package. The custom's back seats feel too work truckish. Seats are not as comfortable. Plus it is pretty plain inside all together. But if that doesn't matter and you want the engine (6.2) then go that route. Not really a bad decision either way, just depends on your wants and needs. Hope this helps you, Kebooble.
