There's a huge market segment who spend $60k on their 1/2-ton trucks. They only use them as grocery getters and as "check out my new flashy driveway queen" in the suburbs. IMO, these are the folks that'll keep the Nissan Cummins a viable product for the short term. Once they become less of a novelty and lose their initial curb appeal . . . all bets are off. It's going to be very difficult for a truck with 1500 lbs. of payload to be taken seriously (in any big way) in the commercial or recreational towing market.
I still have trouble wrapping my head around a truck with a gooseneck hitch that only has 1400-1500 lbs. of payload. It's almost like putting a class IV hitch on the back of a Camry or Accord :(
