I had a 6.0 too. Ran good but did like to be in the shop.
At some point this light duty diesel race has to end. If you need that much truck you need an F-650 with a Cummins or Cat and stop fooling around. And a real transmission.
Engine built to the limits, light duty transmission/transfer case pushed to the limits. Not a good recipe IMO. I guess they are cashing in all the people using a 1 ton to do the job of a 1/2 ton truck or SUV.
