I'm guessing it has to do with the extra curb weight. The new design gained at least 500lbs. IF the GCVWR (Gross Combined Vehicle Weight Rating) didn't change and the curb weight increased then the tow rating goes down.
 
The decreased towing capacity is interesting. Heck, the current Explorer is rated to tow more.
 
Lots of things effect tow ratings. HP & torque probably have the lowest effect on what the ratings actually are. The suspension, chassis, brakes, and transmission etc. are far more important in determining what a vehicle can safely tow. Look at 3/4 and 1 ton trucks. The diesel option does not increase tow ratings over the biggest gas engine.

jnrz -
I have my new performance exhaust on order with Zoomersexhaust (supposed to be shipped 5/26) - I will be able to let you know how it sounds (along with a link to an mpeg hopefully) shortly after that.

Thanks for the info. My old Yukon did not have autoride. What kind of hitch do you use on a Denali? (2" drop, etc.) assuming it keeps level when you hook up the trailer. I used to have a hitch that was flipped over to raise the trailer level on my old truck because the backend would sink everytime I hooked up my trailer.

Same here. I had a 2" drop, that I flipped UP because the boat trailer needed it high. I had a Schuck cushioned hitch.
 
On the new Escalade, I had to change to a 4" drop to maintain the same hitch-ball height. There's a 6" difference.

I installed the GMC performance exhaust cat back single side with the dual wall angle cut tip. My first time with exhast upgrade ---sounds great - gets better mileage unless I am showing off the rumble to the cars trying to race me....

Thanks. What size tires do you have? My new Denali (which I just drove home with ) has 20" rims. Wonder if that would make a difference if you have larger rims for your Caddy. The problem is that my boat is stored away from my home and when I pick it up I will need a new hitch for the Denali.

I love my truck. It is well built and I'm not experiencing rattles and clunks that have been posted here. I've been towing with it and it pulls quite well, better than my 99 Suburban did. There are two things that I would change and dislike about the truck. One is the height of the trailer hitch. It requires me to use a 12" drop that is huge to store and moves around considerably more than a slight drop. Second is the light color of the roof/ceiling material that dirties very easily, especially around the grab handles.

The Escalade has 22x9 wheels, using 285x45x22 tires. The diameter is 26", which is the same as your 275x55x20 wheels.
 
You will have the 5-6" difference (higher) in height from any previous generation of GM SUV. Be prepared.

Thanks Dave, I really appreciate your help. One last question....What is the distance from the ground to the bottom of your receiver on your Caddy? This would help me double check if mine will likely be the same. With the autoride, does this pretty much stay at the same level when you hook your boat up? SJ

The Denali and Escalade are identical in the ride height and suspension. If I remember correctly, the new hitch is 21" from the ground, measured to the bottom-inside of the receiver.
 
When you put the boat on, the air compressor will kick in within 5 seconds, and restore the same rear height.
 
On a side note, I have since lowered my Escalade by 2", by replacing the rear coils springs. This actually makes the vehicle "level". GM SUV's tend to have a large amount of wheel well clearance, and so it has the stink-bug look. I didn't want to alter the front end, since this affects the CV boots, axle angles and such, but I wanted the rear down a bit.
 
I used a Hotchkis "leveling kit", designed for the '02-05 years. Seems GM didn't design different spring mounts. However the 1.5" drop kit created a 2" drop on the '07. Must be some extra weight in the rear of the new generation GMs.
 
The air system pumps up 1/4 inch to make the total drop actually 1.75". The kit contains 2 coil springs, 2 replacement air-ride level sensor rods. Did the whole thing at home in 1 hour, using a floor jack, a bottle jack, and basic tools.
