Best Suburban Specs?

[joeifagroup]

Just bought a 2011 1500 LTZ Suburban with auto ride and tow package. Max tow rating is 8000lbs. How big of an airstream can I tow with a Hensley hitch. First choice is a Classic Limited 27 FB. Our Second choice is a 25 FB Serenity . We need expert help to decide.

I think you'll find both those trailers to be well within the 8000 lb limit. My 30' Classic, loaded and ready to go runs over the scales at 8500 lbs.

I think you're fine.

But the new ones also have a 6-speed automatic, so deeper rear gears are now beside the point.

This is true. 3.42 is fine with the new 6 speeds. More selections for ratios to match load and speed. You'll use 4th and 5th most of the time in flats and rolling hills.

We have just upgraged from our '98 2500 Sub with the 454 engine, 4.10 rear & 10,000 lb touring pacing to a very low mileage, '03 Yukon XL's with the 8.1L (496 cubic inches), again with the 4:10 posi-traction rear & 10K trailer tow package -- both 4X4.
The 454 had PLENTY of hp / torque to pull our '07 25' Safari FB but after 175K+ miles it was time to move on.
After investigation, we choose not to go new since the biggest block now availabe is the 6L -- which someone correctly commented gets its HP and torgue much higher int he RPM range.
As they say, "there is no substitution for cubic inches". The 8.1L engine has both in spades!

Congratulations. I think you'll find as I do that it's a great tow vehicle.
