Ok, not to beat a dead horse, but...
I am wondering about fuel economy of the 6.4 vs. the 6.0 and 7.3 engines. I did a search and found a lot of stuff about fuel economy specifically on the 6.4, and some of the posts had stuff like "my 6.0 got better mileage", but I'd like to see some figures from people who have driven both and see how much worse the 6.4 is. If you can provide figures I'd appreciate it, also axle ratios and whether mileage is towing/empty, manual/auto, usual speed, etc. I am told that a 7.3 will pull what I want to tow without problem (possibly up to 47ft trailer, 2 cars for track, maybe 15-18k lbs), but most of them out there are high mileage and pretty pricey still compared to a used '08, which I don't understand. Also, from what I can gather I should avoid the 6.0...is this true? So far everyone I have talked to except for one person has said stay away from them. Please understand I am NOT trying to start any heated discussion, just want to get as much info as possible. Thanks!
