There will be a lot of “unfair” or “untrue” comparisons put out here in this thread.
Short answer to your question, no, not even a new 8 or 10 speed gasser with 400+ hp will pull like your LML Duramax. But they will do a great job towing. Folks make too much of this and like to be dramatic. I own or drive a lot of different models of trucks and tow with them and ain’t a hill in WA that a new HD gasser will struggle to get over with your camper.
That said, what are the issues with your Dmax? This is a horrible time to try and buy a new truck and depending what’s up with your Dmax, keeping it could very likely be the best decision.
Emissions? If you got it fixed then roll on. If it’s still an issue, no emissions testing here, I’d delete that sucker yesterday and let er rip!
Something else? How many miles? How has the truck been maintained? What would it cost you to move up to a new truck? All factor in.
If you want to discuss the issues with the Dmax and your current thoughts there, maybe some advice could be beneficial to you with your current truck, if you’re not well read on them.
Cheers!

Math. A $1,000 repair each year is like making 2 new truck payments. My truck is 21 years old. I just paid $150 in minor repairs (old cracked hoses). Where would I be able to buy another truck for $150?

Jamesu, if it’s a long bed crew cab, low miles, well kept, I might be interested in it if you’re dumping it for a new truck.

Math. $1000 doesn’t go far if you’re not doing your own work.
Math, if the OP is having emissions issues (likely his frustration), $1000 is just a start.
Math, sitting on the side of the road in BFE is $1000 just to get somewhere to start spending more $1000s to fix it, depending on the problems.

"You know that hill you go up now at 2000 RPM in your diesel? It will be at 5500 RPM in the gasser."

Too sensational! Properly sized gas engine pulling an appropriate weight at a safe speed will be fine.

LOL. And if it's a diesel, for every mile you drive, the tooth fairy will put $10 in your bank account.


The dodge fan boys hate the dodge/ram dealerships. Now that I have owned a Mexican Fiat Oui-Oui (La fiat wee-wee), I understand why.
The only thing more incompetent than Ram is Bye-don and his supporters.

Because of quite expensive repairs on my diesel (see signature) it has got me thinking. I am half way contemplating trading for a 3/4 ton gasser. My diesel tows very well, so I am wondering: would a 3/4 gasser’s towing performance be comparable to my Duramax, or would it be more like a “beefed up” version of the 1/2 ton gasser I used to tow with years ago? On trips I am towing 8500-9000 lbs.

Comparable, no, but more than good enough as long as you accept a little higher engine speeds.

The first reply hit the nail on the head, the right gas engine will do the job, just not at the same comfort level as the diesel.
I think the cut off for a gas TV is really around 12,000# beyond that you suffer from poor mileage, and slower speeds.
I moved from a 2001 Ram CTD, 5 speed and 3.55’s, I now tow with the 2016 in my signature. I can honestly say that I hardly notice our near 13,000# 5er when towing.
As to cost of maintenance yes newer diesels do cost a bit more, $110 for fuel filters every 15k, but I can also go 15k on an oil change, is that two or three times for gas?
I changed the 2001 every 10k miles, I had to replace the tappet cover gasket at 300,000 miles and the gallery was clean!

Heavy duty gas trucks are turds, that's really all I need to conclude to justify a diesel. They're just better from a performance standpoint.

What must one conclude to justify needing $20-30k in comfort and appearance upgrades over a base model?


Describe in detail YOUR experience towing with a modern (2015+) gas-powered 2500 or larger truck. Be specific.

Yes, a diesel is a superior tow vehicle but more complex and expensive to repair. If you travel extensively and especially if you do a fair amount of mountain towing the diesel is for you. If you just make a couple of trips a year and aren't battling your way through mountainous terrain that often then a gasoline engine is just fine.

Just went through this decision. I was looking at a 2020 6.4 and a 2020 Cummins. The gas had more bells and whistles than the diesel and rode really nice. Price was a little cheaper too, both are used vehicles. Did a lot of research about pulling our 10k trailer with something (four wheeler or golfcart) always in the bed. The diesel just made more sense. I've pulled with a Ford V10 and their 6.2. The V10 was a great engine, just thirsty. 6.2 even with 4.30's in it is way underpowered. The Cummins powered truck does have fewer bells and whistles, but runs good and pulls like a dream.
