Has anyone seen a F150 diesel on the road yet? I have been waiting at least 2 years for this vehicle. I am driving an 09 F150 with 320k miles waiting for the diesel. I really hope it is worth the wait. I am pretty much resigned to expecting the F150 diesel I hope to buy being a 2019. I would like to wait long enough for the first problems to be worked out before I buy. Not sure how many miles I have left in my 09.
