6.6L gas or Duramax for upcoming purchase?

I agree...I like quite the older I get. I had an '08 Ford Mustang Shelby GT 500 convertible that I purchased used (2 yrs old). It had aftermarket exhaust on it (don't remember what brand), and I paid my money to an exhaust shop to make it quieter. I never noticed it being slower after changing the exhaust...but it was much quieter and both the neighbors and I appreciated it.

I miss that car!

With the additional cost of the Diesel to start with and the increaed maintenance cost, in my view you would have to love diesel alot to pay for it whn you don't need it...thats what it comes down to. I have the 6.6 gasser 3500 and pull a 32ft travel trailer wth ease

I also have the gas engine. Just curious, what is the typical weight of your trailer when towing? (not dry weight)
 

I never tow and the heaviest thing I put in the bed is my dirt biked but I still went with the Duramax. I've owned 2 gassers and this is my third diesel. I don't know why I prefer it over gas but I do. Yeah it's a lot more money to get a diesel but I'd hate to spend $80K plus on a gasser and each time I walk up to it think "why didn't I just get the diesel".
I love the diesel too. I tow a lot, but nothing the gasser couldn’t tow.

My experience with diesel reliability, durability, and maintenance has been great over the last 30+ years. Yes, they cost more to buy, each service is more expensive, and you have to add DEF every few fill-ups. That’s the end of the negatives. On the plus side, there’s gobs of power, better fuel economy (generally), better durability, and much better resale value (so you eventually get a chunk of that extra purchase cost back). I have yet to hear anybody say the gasser will outlast the diesel. There’s a reason for that.

This isn’t a negative commentary on gas engines. I love them too — but in a truck or a tractor, a diesel is mighty hard to beat.

Edit: There’s one more diesel negative. It’s heavy. If you buy an AT4X AEV, as I did, you’ll be left with a very small payload (less than many half-ton trucks), so it’s not a good fit if you ever want to carry a camper or other heavy loads.

From a farmers perspective, the diesel doesn't run as hot as a gasser. So you can park in a recently harvested wheat field in the middle of July and not worry about the cat/muffler catching the field on fire.

Corn fields are generally harvested later in the season, but I hate to see salesmen, news crews or others pull in with a car or gas truck either way. Most understand, and park on the gravel roads and walk in, but there is always the wild card.

We have enough problems with combine bearings going out, starting our own fires.

NEVER EVER PULL INTO A WHEAT FIELD WITH A GASSER!

This notice was sent out this year. Yeah right, tell a farmer to quit harvesting his paycheck...

If you realy want to carry a heavier payload, should have purchased a 3500 or a dually. No point in complaining about an AEVs payload when you knew its no match for a NON AEV or a 3500

Yeah, I know the diesel is heavier but never considered the huge impact it has when paired with the X trim. I almost got an X but never considered a diesel. Together the Duramax and the X trim make a heavy truck for sure and you cant get the X in a 3500.

But, but, those rims! 🫠

Agreed...However, my AT4X has a much higher payload than my '16 Ram 2500 loaded up with options. That Ram had a payload around 1,100 lbs!

I was responding to the more general discussion of pros and cons of gas versus diesel, not my particular needs. A comparison of two otherwise identically equipped AT4X trucks will reflect more available payload for the gasser. For those who want the AT4X, but also want to carry a light pop-up camper (or similar weight), the difference in payload might make the gasser the better choice.

As to what I should have done, the answer is “more thorough research”. :unsure: I got convinced by the GMC’s great looks, great ride, great turning radius, and better repair record. Collectively, those were compelling, obviously. Of course, I was unaware of the long list of negatives discussed in other threads, but I should have been. I didn’t know what I didn’t know. That’s my fault, and it’s been an expensive lesson.

I don’t want a dually, for several reasons, but the Ford Tremor has about twice the payload, more power, and it fits 37” tires without any modification, so it carries a camper comfortably. That’s enough for my needs.

If I had unlimited money, I’d get one of the custom F-550s built in Colorado. They ride like a half-ton, are super quiet, and can carry more than 8,500 pounds in the bed. They’re also about $200,000. My neighbor’s truck is shown below… The hydraulic suspension lowers to make getting in easy, it self-levels, it corners well on 42s, the turning radius is tighter than my truck, and it’s luxury-car-quiet on the inside.

As it turns out, you can do almost anything with enough cubic dollars. This particular neighbor is a super nice guy. Started from scratch and he’s been very successful. Humble to the soles of his boots — and he’s purchased or built all the toys I’d buy if I was worth $30 or $40 million. 😂

It’s only money; you only live once.
Your neighbors truck, two things I liked, the active suspension and short turning circle if someone is doing that type of off-road. Funny thing, when went to Birkenhead Lake in BC, the 17 mile trail has a few hairpin bends. After a few runs, as
I became familiar with the road, I was able to drift the AT4X on a couple of turns on the downhill run, although I didn’t want to ruin my nice tires. I could only do that because the trail was bone dry and allowed a controlled skid; not something I should be doing with this truck, it’s not designed for it.

I agree. So, if I’d already done everything I could think to do for my wife and kids, and I’d fully capitalized trust funds for all of my grandkids, and I felt good about my level of contribution to local children’s charities, and I was done traveling all the parts of the country and world I have yet to visit, and I had no other higher priorities or wants, I would absolutely buy one of those trucks.
 

Yeah, I know the diesel is heavier but never considered the huge impact it has when paired with the X trim. I almost got an X but was never considered a diesel. Together the Duramax and the X trim make a heavy truck for sure and you cant get the X in a 3500.
Or with a long bed... I was aiming for a 3500 gasser X, but needed that bed space, so I'm X-lessy. My payload is 2 tons and needed that more than what the x offered.
