PSD 2wd - 4wd mpg
Hello,
I am in the process of buying a used 04 - 06 F250 in diesel. I only need a 2wd vehicle but in my area 4x4's seem to be in the majority. Is there any difference in mpg between the two? I have always heard that you lose 1-2 mpg with a 4wd. Is that still true? What is the estimated mpg on a PSD?
Thanks.

Typically there is a difference. The reduced sprung & unsprung weight help. It is around 400lbs+ of weight savings. The lower body also can aid in aerodynamics...yes...I know aerodynamic and Super Duty shouldn't be spoken of in the same post but... 
My 2WD nets better mileage than my previous Y2K 4x4 Excursion did.

Also, because a 2WD has to carry less weight, the towing capacity is usually 500 pounds higher than the equally equipped 4 wheel drive.
2WD Super Duty trucks are somewhat rare. Good luck in your search.

If you ask 10 different people that have 4x4 super duty Fords what their fuel economy is, the answers you get will have at least a 1-2 mpg difference. I get about 14-15 mpg with my F350 SRW, 7.3 PSD, 4x4, AT, CC, LB with a 2-2.5 leveling kit and 315/75R 16 M/Ts. Heck, I get a 1-2 mpg difference depending on what brand of fuel I use. I get the best mileage with Exxon and the worst with Walmart or the junk fuel that they sell on Fort Hood.

2WD is definately the way to go if you dont need 4x4. Yes it will use less fuel. Truck will weigh less so more payload capacity and should be more repsonsive as well because it is lighter. No T-Case or front diff to do maintenance on or potentially fail. 2WD has IFS for better ride quality. I have a 2007 F350 with 18" tires and it will fit inside a standard garage door, not sure how many others with 18"ers and 4x4 can say that.

Yeah it might be worth $1000 more when you sell it but it costs you $2000 (just making up numbers here) when you bought it new.
IMO, dealers like to talk resale value as a way to get the public to buy more expensive trucks than what they initially wanted to before walking into the dealership.
There are people who actually want 2WD for the benifits I listed above. That makes the small numbers 2WD trucks on the market a good thing for those selling them.

EDIT:
Mispelled words are from Wikipedia. 7.3
[I]The T444E is a Diesel V8 engine manufactured by Navistar International Corporation. It was used by Ford Motor Company, branded the Ford Power Stroke engine, from 1994 through 2003, replacing an earlier 7.3 L indirect-injection V8 from Navistar. It was replaced in 2003.5 (After December 31st 2002) by the 6.0 L VT365.
The T444E used a 104.3 mm bore and 106.1 mm stroke. Power output was 275 hp (205 kW) at 2800 rpm and 520 ft.lbf (705 Nm) at 1600 rpm. International built nearly 2 million 7.3 L Power Stroke V8s for Ford at their Indianapolis, Indiana plant before switching to the 6.0.
6.0
The International Truck and Engine VT 365, also sold as the Ford Power Stroke, is a Diesel V8 engine. It is used as the Power Stroke in Ford's F-Series Super Duty and under the International name in the International XT trucks. The 6.0 L Power Stroke turbodiesel was on the Ward's 10 Best Engines list for 2003.
It is a 32-valve pushrod V8. Bore is 3.74 in (95 mm) and stroke is 4.13 in (105 mm). Output was 325 hp (242 kW) at 3300 rpm and 560 ft·lbf (759 Nm) at 2000 rpm, but as of 2005 that was increased to 570 ft·lbf at 2000 rpm. It also uses a 2nd generation HEUI (oil common rail) direct injection fuel system, as well as a variable-geometry turbocharger, which is designed to reduce turbo lag and create better throttle response.
The 6.0 L VT365 replaced the 7.3 L T444E, also built by International in Indianapolis, but has not been as successful. A high number of warranty claims (US$50,000,000 in two years) caused Ford to discontinue their contract with International Truck and Engine to build a Diesel V6 and paying US$70,000,000 to International Truck and Engine as compensation for ending the contract. Ford considered International Truck and Engine rival, Cummins, before deciding to design this new Diesel V6, now known as the DT17, in-house.
Although the engines have been plagued by problems, Ford still sells 250,000 or more each year at a $5,300 premium over the gasoline engine options in its Super Duty trucks. The problems included leaky fuel injectors, oil leaks, and sticking turbocharger vanes. There have been 77 technical service bullitens related to the engine since its introduction.
