I've got a 2005 F-250 HD Diesel and just went through a similar issue about 18 months ago. Mine blew a head gasket after the stock head bolts stretched. Up to that point the truck had been pretty good. The place I took it to charged me 8000 to install a bunch of aftermarket parts on the top end of the engine. It supposedly addresses many of the issues that Ford had with this engine.
The oil cooler is a big problem and the Ford replacement part supposedly corrects some of the issues.
The coolant filter is a cheap insurance. There's a lot of casting sand that's left in the engine when it's manufactured and it tends to clog the oil cooler and EGR cooler. Another issue is if someone added the wrong antifreeze at some point. The coolant going through the EGR cooler is exposed to extreme temperatures and if it's not the correct type it forms silicates that clog the oil cooler and EGR cooler. Once the EGR cooler gets clogged, there's nothing to cool the exhaust gas and it melts a hole in the cooler that allows coolant into the combustion chambers. This usually results in white smoke under accelerations and will blow the head gasket if it gets too bad.
Make sure you only use coolant that meets the requirements for this engine. Using the wrong coolant will destroy the EGR and Engine Oil Coolers.
I had ARP head studs installed to replace the stock Ford head studs. They're less inclined to stretch and cause a blown head gasket, but they aren't cheap. The studs were about $600.
Ford has changed the design of several components in the fuel system after a lot of failures. The shop changed out several parts and pieces with new and improved Ford parts.
I haven't done a lot of towing since I got the truck fixed. It runs great.
One word of warning. My problems were most likely due to adding an aftermarket tuner that increased cylinder pressures. That seems to be a common cause of many of these problems.
