"First Ford I've ever owned, far superior interior and ride to Chevy, but the 6.4 was a BIG mistake. Three DPF's in the first 15,000 miles, cab removed for exhaust leak, #5 injector replaced five times before they figured out the harness was bad, rear differential replaced at 600 miles. Bugs are gone now, but only gets 7mpg towing and 10 empty. Had to add a 90 gallon auxillary tank to go more than 200 miles between fill ups towing."
"This is definitely a mission built vehicle. I pull a 5th wheel that weighs in at 17,000 lbs and this is an ideal vehicle for the task. The cabin is very comfortable and well designed. The truck has plenty of power and has been very reliable. If you're looking for something that rides like a luxury car, this is not for you. If you're looking for something that gets 25 mpg,again, this is not for you. If you're looking for a powerful, dependable tow/haul vehicle, this is your truck."
"We have this truck as a work/farm truck. It has awesome power, great turn radius, luxury inside, but sure takes the fuel. We have the 5 speed automatic. When cruising on the interstate, it could use another gear. 2011 and up do have 6 speed automatics."
"I have the new 6.7 engine i get 14around town and 17 hwy. Havn't towed anything super heavy yet. Mine iskingranch loaded with ac in seats sun roof microsoft sync system, I driveit when i dont need to because it is so comfortable. Much better ride than my 08 f450 i traded for this one. Turn signals weird wontstayon when you want them to and stay on after lane change and come on when u dim the lights"
"I have had my F450 dually for two years. Does everything I ask of it except pass a fuel stop. I didn't get it for its economy. I have a 14000# fifth-wheel trailer and a 4000# truck camper. It movers either of these with ease. I would say though that a larger exhaust system, cold air intake, and a programmer have made this truck a little more economical. These upgrades paid for themselves in less than a year.
The biggest suprize that I had was the handling. Rides nice and turns in a significantly shorter radius than my previous F350 dually."
"I carry a large truck camper. Total vehicle weight 14,000 lbs. It is the best truck out of 9 that I have owned. the handling is superior, the brakes are the best (30% larger than my F350) Fuel mileage at 70 mph has been 8.6 hand caculated for 26,000 miles. I would be pleased if it would be 10 mpg. My wife says it is the most comfortable truck we have had, however it always has the truck camper on it. The little I have driven it unloaded, I found it better than expected."
"Short and sweet, had a 99 F350 and loved it, have an 08 F450 and hate it! Threee radiators, 4 thermostats, 1 transmission, still leaking from radiator, at best 10 mpg if I am careful. Save your money, I have owned a Ford for 12 years and as soon as I get rid of this truck I won't own one again."
"Honestly, I love everything about these trucks but the lousy 6.4 litre. What is Ford thinking? I had an '08 F450, it constantly had EGR issues. Oil leaks. Radiator leaks. DPF filter problems. Fuel mileage got continuously worse. I traded it in for a '09 F450 because I bought the sales pitch about how they're sooooo much better now, the bugs are worked out, yada yada yada. I'm an idiot. Now I have all these problems and more. The catalytic converter is clogged so it has no power, but the dealership says everything is fine. Really? Should an F450 pulling a trailer with only 5000lbs only go 45 mph up a small grade? should it only get 4.5mpg WITHOUT a trailer even on it? Oh, it also has a blown o-ring in the radiator. But the dealership can't seem to find the time to get that fixed. Yeah, Ford rocks. The 2011 seems better, but I'm not convinced yet. They'd be better off dropping a John Deere engine under the hood. Spend your 61 grand on a nice boat. You'll enjoy it more, and it'll probably last just as long. P.S. I had to change a few words to get this to post. I have a potty mouth when it comes to F450 talk."
"In January 2013, I flew from Alaska to Phoenix to get a 2010 Lariat SD with 22,000 miles and drive it back up to Alaska. While passing through Las Vegas I purchased a 24' enclosed car hauler and while in Washington, purchase an Audi All-Wheel that fit nicely in inside the trailer and about 2,000 lbs of sand bags to put in the 8' bed. The 450 had no problem pulling the load, the handling was like driving a car, the interior was quite comfortable with no mechanical or electrical issues all the way to my home in Eagle River, AK. Since then, I have pulled my 28' Trophy to and from Prince William Sound, Resurrection and Kachemak Bays and have seen as much as 17.2 MPG on one return from PWS with my boat in tow. The Seward Hwy into and south of Turnagain Pass if full of long steep grades and frost heaves. On one weekend fishing trip to PWS, I had 4 other men that rode along (I am 215 lbs and the smallest of all 5) even though it was snug for the 3 in the back seat, they all commented on the roominess as not being overly cramped. The weekend resulted in taking home shrimp, octopus, halibut, cod, rockfish and salmon. I have owned a 1967 F250 Custom 2x with a 10' Cab over camper, 1992 F350 4x with a 9' fisher plow and sand spreader and a 2006 F250 SD 4x4. I have been please with the reliability and performance on all of them."
"This truck will pull anything but the pricetag makes it unaffordable for most, the engine has some features that make it less than reliable. Ford has managed to take it's best engine ever (the venerable 7.3)and make it a pedestrian engine (6.4l) that needs constant maintenance and high dollar repairs. The particulate trap plugs up and has a burn cycle built into it. Many take it out and tune it which is about a $1500 add. 19.5 inch tires are very expensive, fuel economy is as bad as it gets at about 13 - 14 empty and under 10 when towing. Expect engine repairs or replacement before 150k. Why would put a 5.4 in an F-450?
The interior is very roomy and can accomodate a family easily enough but for the pricetag you could buy 2 SUVs and use about the same amount of fuel. Then there's the issue of insurance. Try finding an insurance agent that knows how or is willing to write a non-commercial policy for one of these. It's hard to find"
