All that said, Nice set up!
Re: Ford 6.0... I would add,
Keep the fuel and oil CLEAN.
And when pulling the trailer, let the engine idle 3 min. or more to cool the turbo before shutting the engine off.
And after cruising (not pulling) for long periods (an hour or more), before exiting the highway, slow down a bit then and go 'pedal to the metal' for a few seconds so the turbo vanes go from one extreme to the other. And cooling the turbo still a good idea.
I suggest, too, that you add an engine-coolant filter. The factory engine oil cooler can gradually plug up leading to all kinds of problems.
Get some kind after-market gauges to monitor temps and pressures. They may alert you to a problem before an expensive failure.
I've also used Ford's PM-22a from day-one due to improve lubricity and reduce exhaust soot. No way to know if this has made any difference.
My 6.0 has about 314,000 miles and still going strong.
