ROTFLMAO, 425 HP 7.3 diesel??? Stock? LMAO
Where do you people come up with this stuff?:R

The 6.2 gasser vs the 7.3 diesel. The 6.2 gas will leave the 7.3 in the dust, heck it would only be 2-4 mph slower in most situations than a brand new diesel.

Not in my case. I paid $7K in cash for my 99 F550 XLT with 7.3 powerstroke. For what I need it for it is far more economical than my gasser. 94 F350 with 460. Hauling and towing what I do I got 6 to 8 mpg. my powerstroke gets me 12 MPG.
Far more economical and easier to drive while hauling than my gasser.
I keep hearing opinions from those that have no experience to back up their statements.
I drive a diesel Dually because I need it to haul my 4000 lb cabover and cargo trailer, M105A3 that weighs in at 2700 empty, Up the hill to Flagstaff to Phoenix.
Was very tough in the gasser but a walk in the park in the diesel.
Here is I think another case of apples and oranges. I drove an early 99 for over 13 years. Sure it served me well, but I wonder about the statement of climbing mountains with ease. i now tow with a 6.2 gasser because it fits into my needs and budget. However I would never say that the ole 7.3 out performed the 6.2 on the road.
Gassers have a place - diesels have a place
It is a matter of weighing needs, affordability, practicality, and then sometimes whatever toots your horn. :B

The OP is considering Gas to diesel.
I gave him real world experience comparing my diesel to gas trucks.
The very nature of the 2 engines is apples to oranges. You can wonder all you want about going Phoenix to flagstaff with ease all you want but the reality is the 7.3 with Cruise set at 70 with AC on the entire trip.
My 460 with E40D gasser was spending time in second and 3rd gear to do the same thing.
My examples are based on Hauling a 4000 Lb camper and 5000 Lb trailer in both cases over the same road. It sounds as though you are referring to an empty 6.2. How do you think the 6.2 would compare to the 7.3 loaded to GVWR?
where we do agree is "Gassers have a place - diesels have a place" And to each his own.

Experience with maintenance and repair varies by make and model year. Since 2003 there have been 5 different Duramax engines and most have had problems that necessitated a redesign. The current LML is no different as it is the first to have the DEF and NOx sensors and the sensors have not been especially reliable and problems have been very difficult for the dealers' service people to diagnose correctly and fix. Many posts on the www.duramaxforum.com website.
Older Ford diesels had their problems and Dodge trucks have not been trouble free either when you consider all the truck's components including heating and cooling systems and emissions and electricals.
The biggest difference with the new diesel engines is the need to change the oil and filter more often and to use twice as much oil with each change. Overall not a big difference. When repairs are needed it can be both very expensive and often difficult to get items covered by the manufacturer warranty without a battle - in particular with regard to the emissions system's components that are supposed to be covered by federal law - not that the corporations care about the laws.
Diesel is also more of a problem in very cold weather with the potential for fuel gelling (worse with today's bio fuels) and longer warm up time. Fuel economy is at its best when doing heavy hauling or towing or at freeway speeds, and at its worse for short trips and around town driving.
I get better mileage of course with my 2011 Duramax diesel but with the higher purchase price for the truck and the higher cost of diesel fuel my breakeven point is after more than 200,000 miles.
But for dealing with heavy loads the diesel engine's torque and engine braking are exceptional benefits. Just don't try to rationalize the decision as so many people feel compelled to do. No free lunch in effect.
Used diesels are another story altogether and for the price on the used truck market they don't offer much in the way of value for their new owners. Some people get luckly but many do not and repairs on most diesel engines are a great deal more expensive than with a V-8 or V-10 gas engine.
