last time I looked it was the slow burning nature of diesel fuel in the combustion chamber and the push all the way down the cylinder thats creates TQ.

Lol. I can haul as much and more than any gas engine. Easily and with less effort. Diesel fuel is everywhere. I have an extended warranty so repairs aren't an issue (Haven't needed a diesel repair to date (knock on wood)). No block heater required; even in sub freezing temps. I love the fact that I hold 5 more quarts than you.

How exactly can you haul more than any gas engine? Your GVWR doesn't exactly say so or the DOT laws. Nor does the fact that you can get a gas silverado with the same axle, springs and tires, and less curb weight. Doesn't make a whole lot of sense.
I have seen plenty of fuel stations that don't carry diesel. Many more only have one pump that isn't a dedicated diesel pump but shares it's spot with a gas pump that may be in use by a gas vehicle. I can bet that more often than once a diesel owner has had to wait for a vehicle to be moved from the one available pump.
Funny that you felt the need to pay extra to hedge against the possibility for a very high dollar repair on your diesel engine.
You may not live in a climate that is cold enough to need a block heater and diesels have gotten better but for some climates it is still a concern.
I'm glad you're happy to have to buy more oil???

The owners and drivers of camper delivery companies (owner operators), might need to rethink buying a gas motor tow vehicle since they are by far a better platform for towing. and I mean (better platform) as less cost to purchase, operate, service. ect... Why in the world would anybody need a diesel?? if everything in these posts point out that the gas tow vehicle is superior in every category.. But I guess if you make money driving, you buy something that will last and make money to feed your family, this a a RV forum and I would bet every member has a camper and it prob was delivered to a dealer by a diesel equipped tow vehicle. Indiana to the upper parts of canada and the north east is a long way to tow and not make money doing it.. 1 thing I forgot to point out these delivery companies don't allow gas tow vehicles according to my step dad that used to drives out of elkhart with campers in tow

To try and answer a sarcastic question in an accurate manner as best as I can.
The 3 mpg or so mpg advantage a diesel engine has adds up over 500k miles. While the design life of a pickup engine either gas or diesel is much less than 500k the life also has lots to do with the operating parameters. The miles are put on in a short amount of time and time is as much a killer of engines as mileage. The engines aren't started and stopped very often lessening start up wear and probably average 60 mph while running while an average use engine might average 30 mph. So at 500k miles they have the same amount of hours as a 250k mile engine, add to this very little stop and go and it increases the likelihood that in this application your truck may live to high miles and get a payback from the fuel economy. Remember the fuel cost payback is a lot of miles. If you anticipate a lot of miles then you can get the benefit of the payback. Most rv-ers won't own the truck long enough for a fuel cost payback.
Gas vehicles used as taxi cabs and courier vehicles also can live to see high miles for some of the same reasons.
Other possible reasons are that everybody else uses them so that must be what you use. Remember diesel a decade ago only cost 4k more than gas and got 5+ mpg more (pre hp war and EPA) and were far less expensive to repair than the current ones. A much better case could have been made for diesel a decade ago than now, but old wisdom can live on.
Another reason may be the expectation that a pickup diesel lasts longer with or without supporting evidence. Even with design lives within 20k miles of each other between diesel and gas there is strong support among the members of this forum that light duty pickup diesels are "forever" engines. I'm sure this belief is held elsewhere.
It may also be auxiliary fuel tanks are legal on diesel and not on gas. Stops at the pump cost time and time is money.

It's a different world these days. The EPA, inflated Diesel prices and the stupid HP war are crippling the major advantages of the Diesel power plant in light duty pickups. I know a guy that says he will hold on to his 2005 Cummins powered Ram 3500 until it rusts to dust.
The school district that I work at has dropped all diesel vehicles except for the full size busses. They say the Gas engine trucks are much cheaper to operate. They pull some heavy loads ranging from 4 zero turn mowers to flatbeds with loaders on them. They also travel all over the county every day of the work week. There are no state requirements on duty life for vehicles that do not transport students and since we are a pretty poor and mostly rural county, they tend to run every drop of life out of the fleet. I still have to drive a friggin Chevy 30 Van around every now and then. They sold the diesels after they were 5 years old or so after doing a cost of ownership study. I'm sure they did get a pretty good price for them at auction.
If you want to have a diesel and can afford it, get a stinkin diesel. They are great trucks. Not too many people really need one or would really see any benefit but there is an emotional element there to be sure (*Kinda like when people put that big "TURBO" sticker on the side of their car). You still can't beat having a super reliable forced induction engine in a truck. Hopefully soon we will have the benefit of having the choice of a reliable gas powered turbocharged engine in a Super Duty truck.

My point is my diesel has the power to haul any load better; quicker, safer and more economically than it's gas counterpart. I'm not a commercial vehicle so I'm not worried about the weight police. When you order a Diesel (and big block before it was discontinued) you got the Allison and a heavier duty rear axle. It is not the same as when you egt a 6.0. Never had a problem finding diesel and everyone at some point has had to wait for fuel. To suggest otherwise is just silly. Where I live we het down to the low single digits; never had a starting issue; never plugged in. Don't be a hater.
