Keep the 7.3 or get a 6.4 ??
Looking for opinions from guys that have 6.4's before I make a change. I have an '02 F550 4x4 crew cab pickup conversion with a 7.3 and 4.88's. I bought the truck to replace my '06 F350 6.0 truck because I needed something with more capacity and also didn't trust the 6.0 for heavy long distance towing. The F550 is great, I love it for towing, very reliable, etc...........no complaints about the truck except it's not as comfortable for a daily driver as I'd like so I ended up keeping my '06 6.0 truck to drive daily because it's just so much more comforable. Doesn't make sense to have 2 crew cab dually trucks IF I can get one that will serve both purposes. I'm thinking of making a move to an '09 or '10 F450 4x4 pickup as a compromise that will be closer in comfort to the F350 but have the beef of the F550. On the other hand I don't need a truck that is always breaking down and I read all kinds of horror stories here about blown 6.4 engines, etc. Maybe the majority of people that post stuff on internet forums are the ones with problems and there's lots of 6.4's that do just fine? I don't know. I'd probably do a DPF delete and Spartan based on what I've read. So the question is will a 6.4L truck be a relaible 200k - 250k heavy tow vehicle assuming it is maintained properly or should I stay away? Another related question...........am I getting the correct impression that a majority of the 6.4 problems are happening on '08 trucks vs '09 - '10? Did they get it figured out on the later trucks? My other thought is to replace the 6.0 truck with an Excursion or SRW SBCC truck for the daily driver and keep the F550 dedicated as a tow vehicle.
Any feedback from guys driving an '08 - '10 F450 as a daily driver and/or using one for long distance heavy towing would be great.
