OP here,
Great comments everyone.
I do want to clarify one thing
I'm in a 2015 suburban rental. I am not personally interested in a Suburban at this time.
My point in posting this was to serve as a resource for anyone interested in anything on the 2015 Suburban since I have this thing until Monday morning. Any measurements or pictures I will be happy to post.
As far as the capability of this thing I have no doubt that the truck can pull up to its max rating on trailer weight. The tires would have to be aired up to max PSI to get the squishy feeling gone.
I may do that when I fill up and just see how it rides.
I agree with BenK, a 2500 Suburban is well suited to pulling a heavy trailer. But those searching for new will have to accept the limitations of the new Suburban.
FWIW this LT Subutban (loaded with a lot of options) has a little over 1600 lbs of payload and an 8300 lb tow rating. Many of the older 2500 Subs that I looked at had 1800-2200 ish lbs of payload and 7,000-10,000 lb trailer weight rating.
Not a huge disparity in capability
Especially when you compare semi float rear axle 2500 Subs to these new ones.
I've taken some pics and I'll try to post them up for review.
Thanks!
Jeremiah
