My two cents on the V6, 8 speed tranny, and higher end uConnect:
All three of these items are new for 2013 in Ram, from what I understand. One of the things my grandpa passed on to me was to NEVER buy a first year model of ANYTHING, that is, unless you want to be frustrated and like being a guinea pig. So, other than the non-optional uConnect 3, the all-important mechanicals of my truck have been around for years from what I understand.
From what I was led to believe from the dealer, the V6 will not get 25 mpg UNLESS it's in the HFE variant or standard cab. I realize that the Ram website shows all sorts of configurations and trim levels (like the Quad cab SLT) getting 25mpg hwy but just how does a quite a bit heavier quad cab get the same mpg as the smaller and lighter(?) standard cab? I went to the dealership to drive a V6 but they weren't available and perhaps they told me this to sell me one of the 5.7's off their lot?
8 speed tranny isn't new, but it is new for Ram and in a truck (correct me if I'm wrong, also told this by dealer). In five years if I need a new truck and the 8 speed is still around, tested, tried and true, AND it shows to be an asset to either load pulling or efficiency, then I might consider it. I do pull minimum 2 to 4.5 tons quite regularly and know owners that prove the 6 speed holds up well.
I have heard this from this site: You cannot install an aftermarket radio in the 2013 Rams, yet, due to some integration issues. Dealer wasn't certain when I asked this but every 2013 on their lot had one of the 3 uConnect systems. As I stated in another post, I don't like integrated electronics at all. Sure, if it's been around for 5 years and all the bugs ironed out and it doesn't cost an arm or leg, might take the risk. I did not want the "higher end" uConnect models mainly for the price and lack of benefit for me since I have separate bluetooth and gps components that frankly, work better from what I saw in my limited play time at the dealer. I don't want my whole truck in the shop for days because the blue tooth or navigation mode is "kaput". I'm weird this way.
I lucked out getting the Express since I was wanting a Big Horn or Longhorn as the latter seems to have vastly reduced load capacities from my Express 4x4 (I'm assuming the Big Horn is in the same boat, anyone verify?)
So look at all the stickers on the truck for loads and towing and make sure it's within your parameters.
