Hey I was wondering if anyone could help me I'm trying to find out what kind of milage I will get with a F550 with the 7.3 diesel 6spd and al flatbed. It's an 03 with about 11,000 miles on it. I was also wondering where would be a good place to get a value of the truck? I looked at KBB and edmunds but I cannot find the value of a 550 on either site. Thanks for the help

 

One site you can check it Ebay, do a search for completed auctions on a like vehicle and you will get an idea as to what people are paying, willing to pay and or asking.
Or you could look up a like truck but in a F-350 and deduct 15 to 20% due to it being an F-550. F-450 and F-550 have a greater depressed and limited marketability due to demand in the used marketplace. Unless it is a custom designed hauler set-up or the needs or hauling high dollar RVs or horses....for some reason these people are willing to cough up the extra cash for a Cowboy Cruiser Truck.
Now with such low miles on this truck you may want to just price it as a equally equipped F-350 dually truck of the same class (xl, xlt, lariat)
good luck.

 

That thinking is a little backwards here. The 450-550's are worth more in Chicago than a pickup. I've been offered 21,000 for my 03 F450 flatbed with 142,000 miles and it's a plain XL with V10/6 speed!
