Mine is an '07 and doesn't require.
To continue off topic, my '08 doesn't require DEF either.

LOL! Maybe it depends on manufacturer.. I know a DEF delete is pretty common with newer trucks as well.

I'm glad you're happy with the truck's performance but I have to disagree with the quoted.

This spring we did 2800 miles with a 2017 6.0 gasser, 9500lbs trailer and two kayaks on top of the truck making it an aerodynamic nightmare. On the return trip we went from the southeast corner of TN to west central WI in one day. Averaged 7.5mpg for the entire trip and I set the cruise above 70 whenever possible. Did the big grades in KY and TN with only one slowing the truck below 70. I don't know what gear ratio you have but my truck loved to be in first overdrive (5) at 72-74mph and would pull most hills in 5th. Large 'hills' and grades required 4th gear but I didn't think the truck was 'pushed' at all.

At any rate thanks for the write-up.

But the minute someone says the word 'gas' in one of their precious diesel topic threads...

They get tossed off of the playground!

We find traveling below the speed limit relaxing as well. Everyone is passing us but we don't care.

The tires on our 5er are speed limited to 65 MPH. We have found that dropping our speed to 62 MPH, a 5% decrease in speed gets us a 10% increase in mileage. We arrive 5 minutes later for a 10% savings, add to that the relaxation factor and we love the easy relaxed trip.

Yup.....Diesel to Gas here too.

Had a 2006 Dodge 5.9 Cummins and just bought a 2018 Ram 6.4L gas.

Only towed a few hundred miles so far (GreyWolf 19RR Toy Hauler / 7000 pounds). Very pleased with performance. Not too many hills so far, but averaged 12 MPG at 65 in Tow/Haul mode. Diesel is 50 to 75 cents a gallon more in my travels. Every time I fill up I put $15 - $22 in my pocket. MPG not towing is identical for both trucks (17.5). Towing the diesel got 2-3mpg better. (12 vs 10)

Sure it's not a diesel. Lots of shifting going on and that took some getting used to after 12 years of a steady 1800 RPM and rarely downshifted.

Seems like diesels tow on the engine and gassers tow on the transmission.....

The Ram 6 speed in the new truck is wonderful. Very smooth shifts and no drama. The engine is very strong and very smooth. And quiet! And the ride can't be compared. The new truck, unloaded rides like a Cadillac. The old truck was terrible......And the new truck has over 1000 pounds more payload! Gotta love coil springs!

I'm leaving on a few thousand mile trip on next Tuesday. Will be traveling the hills of West Virginia and then out to Oshkosh and back to New England.

This will be the real test.......We'll see if I made the right decision.

I just finished a 3 month, almost 8000 mile pull around the western US of A.

Towing my 2015 9900 pound 5'ver with a 2015 Chevy 2500HD gasser with the 4.10 rear end.

Paid both of them off a few days before I headed out on this journey, and half way through bought a new home in a place I never would have imagined I'd ever visit...let alone buy a home!

That's paid off, too!

Anyway, there are times I wish I had an exhaust brake, but I do know how to drive in the mountains without it.

Averaged around 7 mpg and had the oil changed about three weeks ago because it was time.

I have no regrets buying the gasser!

If I had bought a diesel I probably would have bought a bigger, heavier, and much more expensive 5'ver.

But who needs that?

Would have been nice had I continued to full-time in my 5'ver, but I was quickly realizing that living in the RV was taking away from the charm I got it for in the first place...

Camping!

Diesel verse Gas

We just got back from a trip from our home in Arkansas to Nova Scotia. We have a 2016 GMC 2500 with 6.0 and a Windjammer 3029W which weighs around 9000 lbs unloaded, so close to 10000 loaded. We drove 6800 miles. At between 60 mph and 65 mph I got somewhere around 8.4 miles per gallon. I am happy with the 6.0 Gas and the 3/4 ton. Last year I pulled another Rockwood that was 7000 lbs 11,000 miles to Alaska and back and got 8.7 mpg on trip. I will say the 3/4 ton is a big improvement over the 1/2 ton on stability. The truck does great unless it is a big grade. On an 8 percent grade it groans but it does pull on up. I do not use a WDH hitch because I cannot tell the difference. I use just a regular hitch with a sway bar and it does good. I have had very little sway. On Alaska trip I used a Husky Centerline WDH hitch and when I upgraded to a 5 foot longer trailer I tried the regular hitch and sway bar and it did great. The GM manual actually said that the WDH was optional. Sorry to get off subject.

Are the new diesels leaps and bounds better then ones 14-15 years old ? I'm sure the gasser's are from what I have been reading here on the forum.


Yes I enjoyed the post but will say age/ technology would blow your mind I actually think newer Tundra would really have surprised when comparing to older diesel the 2014 I had was producing more hp and like 10 less ft lb of torque than the new 6.2 by ford but in a lighter truck with 4:10 gears which are about what diesels from early 2000s did now todayís new truck average around 430 hp and 930s torque

A tuned 06 Duramax will get 12mpg, with 17,000, gross.
14.7 with a slide in camper on back, weighing, 2200.
I like the old school diesels.

My buddy, who's job was managing a fleet of diesels with reps from the big three started with the pre-emissions ones...after several years with increasing down time on the NEW SCHOOL diesels they switched everything they could to gas and have never looked back.

A private local sewer and water company dumped their diesels and switched to gas also. That company now seems to get all my cities bid work...

Just got back from a 5 week Midwestern trip.

Ozark mountains, Colorado, Wyoming, and the black hills. I was surprised how the tow haul did most of the braking.

Pulling a loaded 12,000 fiver(likely #15,000). The Ram diesel got overall 11.3 mpg for 4,000 miles.

Mom drives it every day to work a whole 3/4 of a mile.

We get 20-24 mpg on the highway. 75 mph/65 mph. Around town it gets 14 mpg. in normal driving the DEP usage is about 1,500 miles per gallon. When towing closer to 400 miles per gallon. DEP at truck stops is half as expensive than at Walmart.

This modern diesel is beyond my expectations.

Might have seen you along the way.

I just got home a week ago from a seven week trip that included Colorado, Wyoming and South Dakota, plus all the states between there and Arizona!

It just hit me the silliness of this constant argument. There really isn't much difference between gasoline and diesel. It's not like one moves with oars and one with sails, they are both internal combustion engines. The differences lie more in the turbo charging, direct injection, compression ratios, etc. At what stage the gallon was pulled down at the refinery is no magic trick to the perfect fuel. Gasoline is just diesel with a few other things refined out. You can make a high compression, high boost, direct injected gasoline motor and it will put up some silly high HP ratings. Shake the earth type motors. They wont last a million miles and they would use more than a million gallons doing it. I think where diesel got ahead was when they were allowed to be more outside government regulation. Diesels used to basically suck, but then again so did gas motors. Gas motors then got really good and the government stepped in more and more every year. Diesels were left alone and they closed and surpassed the gap. Now manufacturers are getting ahead of the government on gas motors and the government is starting to push on diesels like they did on gas over the last 30 years. How it will wash out, who knows? They both are at a pinnacle of engineering, the all time best internal combustion motors ever made.

That must be why the big rigs use gas engines. Maybe you should see how much torque gas engines puts out at 1400 rpm then you could better understand the difference.

Now if only someone made a 13 litre turbo charged gas engine so we could find out. I just don't understand oil burner owners incessant need to make themselves out to be superior to gas engine TV owners. Guess it makes you sleep better at night.
