Wow. Talk about an arrogant attitude. I have a gas, I can afford a diesel, I don't need a diesel for 10K lb trailer. Would it make a more perceived enjoyable drive? Subjective.

It's not a matter of affordability but that of making a sound financial decision based on needs and wants.

For someone driving a 250HP, 505TQ, 13 year old diesel, you sir need to take your nose out of the air.

Here's my 2 cents. In preparing to re-enter the RV world with a new 37' TT, I decided my '96 2500 12v Cummins lacked the space for my growing family of 4 + 70lb pup. So I sold it. I looked at both diesel and gas pickups with caps and 3/4 ton SUVs for the past year.
I have owned or been issued from work (9) 1 ton and 3/4 ton pick ups for the 24 years I've been driving in both gas and diesel from all 3 domestic manufacturers. I could care less about who made my truck as long as it is reliable and easy to work on when I need to.
I read all the forums until my eyes bled on the gas/diesel debate. I spent countless hours trying new calculations to figure the most cost effective and reliable vehicle that would fit our needs.
The only solid conclusion I could come to was that the EPA has ruined HD trucks as to their reliability(diesel)and tow ability(gas). The premium $ on pre '07 diesels is stupid high and newer gasser lack the displacement to do the job.

I went with a 2003 F-250 7.3L diesel we will use full timing in 4-7 yrs from now and off and on till then. the truck is basically stock and with 168k miles i need to do a couple five to 10 things to get it ready for the road.

while many may say that is a bit old, but i feel the older units are better in some way than the new stuff. The 7.3L engine is used in many application from dump trucks to school buses so the technology is proven and replacement part readily available most all over the county.

you get rid of the DEF and regen stuff and the EGR components some of the new stuff has.

The new ford 6.7L are going to need 5 or so years to get all the issues worked out but by then they will change the motor and you have to start over on the issue front.

Other than the interior the engine, trans, rear-end can be completely changed out with new or rebuilt, plus the interior can be redone as well.

as the diesels make more headway in the states more and more will be available at better pricing.. the diesel premium at 5-8K is a bit much and will be less and less in time.

I have to disagree on one thing.The newer gas HD trucks will tow your tt pretty good. A lot better than you 12V Cummins did.

The reliability of the new diesels is still there they are just going to have to get the bugs worked out of them just like they did with the gas motors when the EPA hit them.

The aftermarket tuners are starting to get a hold on getting the new diesels running more efficient and cleaner and still getting good power gains in the meantime.

Imagine having 500 hp with all the EPA stuff still passing the tests and still running quiet with the factory exhaust. It's here!

The Cummins 5.9 and 6.7L are rated for 3400 and 3300 rpm in marine applications. Cringe doesn't cause excessive engine wear. Strange how people brag about how tough their diesels are yet they believe running them in their normal operating rpm range will hurt them.

The job gets done at 2000 RPM or lower and on occasion short burst of 2500. I've never "had to" go over 2500 rpm to hold a respectable speed and I tow over my listed GCVWR and well beyond the GCVWR of a comparable hp gas truck.

Like I've said before, 2000 rpm is going to be half the wear of 4000 rpm. If you say that today's engines have 0 wear at 4000 rpm then I am getting negative wear at 2000 rpm.

Take a gas truck with 325 hp and hook a high profile 18,000# load to it and take it up and down the road for 100,000 miles holding the posted speed 95% of the time and tell me how she's doin' after the 100,000 miles. Then try it with 25,000#.

I know that most RVers don't pull that kind of weight but this thread is gas verses diesel, right?

I currently drive a 07 2500hd 2wd CC for work. It has a 6L gas burner, gets an average of 14mpg and is dog slow. Both my 12V's and my 7.3 Powerstroke would walk away from this thing @ 19mpg. My "new" TV is an 03 Yukon with an 8.1. It averages 13 mpg.
One more thing to consider is repair costs on the higher pressure injection systems and even worse catastrophic engine failures on the newer diesels. Nothing is even what I would consider reasonably priced for working class people anymore.

If your 12V and 7.3 was stock, the 6.0 LS motor in the chevy would run off and leave them both pulling the same load. It may see like a slow dog to you because it don't have any getty up and go untill around 4000 rpm. I know this engine pretty well. We have 2-2007's at work. One is a Classic and the other is new body. They are very tough engines.
