honest advice on a truck for towing 10000lbs

I think the maintinace issue is owner related. Some that put a lot of miles on theirs will pay more. I only drive 10,000 a year so for me it's not much to put 1 fuel filter on and have one extra oil change. $130.00 more a year is not twice as much as a gasser. How about those guys with the 5.0 Ford F150 that takes 8 qrts of semi syn oil? That's more than the 6qrt non syn gassers. Not much but that's the point. Some diesels are cheaper to maintain than others.

Biggest issue is when water destroys the HPFP. Then all bets are off.
