ksss, you would be a smart man to hold out, at least until mid year. That way any major bugs should have showed up by then. The early 2014 Eco-Diesels had a few issues that showed up right away and had a few customers not to happy with their trucks. The engine had been on the market for some time, just not in the US market.
That was the number one reason I waited until 2015 to buy mine. If I'm going to be a beta tester they are going to pay me not the other way around! At $50,000+ for these trucks I'll let someone with deeper pockets find the flaws.
None of the manufactures do testing anywhere near what they should be anymore IMO.
