Hi folks. I just test drove a 17 Suburban LT that was pretty well optioned out and included the max trailering package.

my question is should I hold out for the premier trim? I’m interested in the Magnetic ride to help control body roll and wallowing on the highway. I really liked the 3.42 gearing the max trailering gives you, but am curious if others find it hurts mpg vs the 3.08.

any other thoughts would be greatly appreciated. Thanks!

 

I would not tow anything with a 3.08 axle ratio unless it was very light. The 3,42 is even a bit light for many trailers. Your Suburban is not a car, it's a large SUV. Going too high on the axle ratio could cause premature engine or transmission failure.
If you want high gar milage you wont get it with a large vehicle. You need to accept this as a fact, becuase it is.

 

How heavy of a trailer are you pulling. Max package is fine up to a point, like when you need to be in a 2500 or 3500 pickup. Tow rating max it just that, the max, and I wouldn't be pulling anything with less than a 30% cushion under the max rating.
3.08 is for pulling a little trailer with stuff going to the dump or a lawn tractor to mom's to mow her lawn.
As said, big SUV / truck means it likes gas period.
