Road Geezer... I believe that you will be very well-served with the 3/4 ton Duramax/Allison option. There is significant "headroom" with this option.

Numbers-wise, we could have stayed with our Yukon Denali towing the 30' Flying Cloud, but in the end, I believe it is better to go with more capability, rather than with less and that is why we, too, are choosing the Denali 2500HD to pull our 30' Flying Cloud.

Hi Bruce

the issue is how many degrees off a straight course can you turn in a very short distance without losing control of the vehicle due to oversteer. Or, put differently, how much steering angle will the vehicle's front wheels accept at highway speeds without the driver losing control?

Basically this is what we are testing with the slalom and lane change test. I get a call or two from customers every year telling me how their combination was able to avoid an accident so it does happen.

A few years ago one of our customers told me about driving through Atlanta. His wife was driving their Astro Van towing their 25 classic. They were in the right lane when just ahead of them a driver in the 3rd lane made a lane change into a car in the second lane just ahead of them both cars started spinning out of control right in front of them.

He thought this is it were going to crash. All of a sudden his wife wiped the wheel to the left tires squealing into the left lane then back to the right around the cars. When he got his breath back he said, how did you know you could do that! She said I watched the video at Can-Am.

Denali 1500 w/6.2L vs. Denali 2500HD Duramax

Most over correction accidents happen because the driver has not trained him or herself to always STAY COOL, and NEVER freak out.

Too many folks overestimate the size of the tow vehicle in safe towing, not quite understanding that tow vehicle mass is not superior to a well thought out and executed combination of tow vehicle and trailer.

Yes, there IS more than one way to skin a cat.

I was in a very similar situation Ė owned a 2015 F150 KR with all the options. Loved it! Then bought a 30í FC. I was way within the towing specs (even the real ones for my truckís configuration, not the TV ad ones). While it towed ok, it did strain a bit on hills and depending on grades, I felt uneasy on downhills. But as mentioned in other responses the biggest challenge for me was payload. With a trailer tongue weight of around 1k, fuel, my wife and myself, we were at the vehicles GVWR limit. And we had not even added items in the bed of the truck. And I had to play a lot with the weight distribution to get weight off the drive axles since I had exceeded that. I spent a lot of time at the CAT Scales. I know the 150 wasnít going to just break, Iím sure I could have dumped 500 more pounds on it but I was already nervous, beyond my comfort level and could feel a strain on the truck as I towed. I ended up trading in the 150 for a new GMC Denali HD with the Duramax. Night and day! I could spend hours talking about the towing difference, the 3/4 ton made it a much better experience. I went through the Blue Ridge mountains with ease. Downhills were no trouble with the exhaust brake, at times I even had to give it gas to keep going! I could carry all the gear in the bed with no worries. The only towing issue I had was on highways forgetting at times I was towing something until I looked in the rear view and saw a trailer right behind me! Now, this isnít for everyone Ė the ĺ ton is bigger, harder to park in cramp areas. But the ride is not bad, not as great as the 150 but very nice. And the gas mileage is as good if not better than the 150 (I had the 3.5 eccoboost). I was getting 15mpg towing, 19-20 on mountain highways when not towing. Get around 15-18 around town. The higher cost is a factor but fortunate for me I was able to handle that (you donít have to buy new). I will say that the 150 had way more features including the one that I REALLY miss, keyless entry, start. But Iím glad I made the switch.

2015 GMC Denali 1500 truck with the 6.2L engine - 9,200 lbs. towing capacity 1740 lbs. payload
2015 GMC Denali 2500 truck with Duramax - 13,000 lbs. towing capacity 2793 lbs. payload

Aside from the $6k-$7k price difference:

The 1500 would have more than enough capability for pulling the 30' Flying Cloud, no problem, and is more "car-like" to drive around.

The 2500 HD is more "truck-like" to drive around, but its extra margin of towing capacity would be very reassuring. I do like the extra height and more truck-like quality of the 2500HD. And the fact that this truck could tow something heavier than an AS, should I ever want to do so, though I don't anticipate having another RV after a 30' Flying Cloud.

I'm told that late model 3/4 ton diesel trucks are in greater demand and tighter supply than 1/2 ton gas trucks are, which may indicate that the former could hold resale value better over the coming years.

I drove both of these trucks today and really liked them both, though there was a marked difference in "feel" while driving them. As I said, the 1500 with 6.2L was quite car-like and the 2500 with Duramax was quite noticeably a very beefy truck, but still quite luxurious and comfortable.

So... your comments about either or both of these trucks would be appreciated.
I had a 2500 Duramax and grew to love it for commuting. If the difference is only $6k you are getting a good deal. I drove the 6.0 gas before buying that truck and it was fine too but the Dmax was a little quicker off the line. As far as parking and handling in traffic there was no difference.
