What do yo know about an 09 6.4 Ford Diesel?

I have an 09 f250 with a 6.4 that has right at 70k on it. I deleted and tuned at around 30k. Unloaded mileage around town is from 11-13 depending on mix. Highway the highest I have seen is about 16. The power tuned is phenomenal and the shifting is on point with good tuning. Loaded with my 5er at 15k I get between 8-11 depending on the mix. I have only had one issue with it that required a dealer, the tstat housing leaking. Other than that, it has been reliable to date. The fit and finish of the interior IMO is light years above the dodge and chevys of that year range as well.
