Well... let the adventure begin. I traded my IH 4700 for a very nice 05 F-450 Crew Cab Fontaine toter conversion with Link MFG rear air suspension. Ultimately this will probably wind up a Cummins conversion but for the time being the 6. 0 stays put. The truck is a lodaed Lariat 30k cgvw rating truck with only 45k on the clock (can easily handle the 4300 lb. pin weight of my Teton. Full Banks mods except the air cleaner. I like the truck part of the truck as the cab is very quiet compared to my 01 3500 with respect to wind noise and seat of the pants comfort. The truck actually runs very good and has been exceptionally maintained. I have done some of the mandatory reliability upgrades like having Bullitt Proof Diesels EGR cooler and remote external oil cooler/filter system installed. Excellent products which replace the most failure prone sytems. It'll never be a good ol 5. 9 Cummins (at least till the transplant) but so far (which is not very far) the complaint list is short. I will say that many of the common issues, according to IH, not Ford or Ford haters or loyalists, seem to relate to lack of maintenance, bad engineering with respect to the egr cooler and oil cooler system which is, well frankly, poor engineering at best. As far as ease of repairs, what a nightmare to get at much of anything under the hood. Even on the 6. 0's cab removal is almost mandatory to remove the heads (can be done without but not the easiest). Fuel milage is actually better than I expected. After about 400 gallons used avg hwy only (hand calc'd) 15. 7 mpg within 2/10 of the computer reading not towing (4:88's at an avg speed of 65). City/combined seems to avg about 12-12. 5mpg. An interesting side note is that people that baby these trucks (drive them real easy for mileage issues or ???) apparently have more problems than those that regularly drive them like they stole them. Driving them too easy apparently cokes up the EGR cooler and VG turbo vanes. That said if you try to get too much out of the 6. 0 with performance addons, headgaskets and ARP studs are mandatory (more so in the '03/'04) due to streched headbolts from the high combustion chamber pressures. All in all the 01. 5 CTD 3500 stays in the fleet cause (sentimental value aside) it's such a good workhorse, gets 20+ mpg on the hwy and has never let me down. The 450 will be used primarily as a tow mule for my heavy 5'er.
