[Autox] Suburban 6.0 2500, how do they tow?

[John A. Carriere]

Hi Larry,

I do not know how recent your experience with towing with Chevy 
products is, but I have to disagree with your statement about needing 
extra equipment.

I had no problem towing an enclosed trailer with a Chevy Express van 
with a 6.0l six speed.  Don Elzinga and I towed from Michigan to 
Lincoln on-cruise control and never opened up the torque converter 
clutch!!  We got 13 MPG!!

Regarding Suburbans,  I thought I'd ask someone who does trailering 
validation testing at GM.  Here's Greg's reply:

John,
The 2010 3/4 ton Suburban with the L96 6.0L engine has a maximum 
vehicle weight of 8,600 pounds. With the curb weight for the 2WD 
model, C20906 around 6,040 pounds there is a maximum payload of 2,560 
pounds for the vehicle. The maximum trailer weight for this truck is 
9,600 pounds. The maximum combined weight (trailer and vehicle 
combined) has been evaluated in some of the most extreme conditions 
in North America, including Townes Pass in Death Valley, CA. during 
the hottest summer months. This evaluation is considered the most 
extreme for worse case grade and temperature conditions. These 
evaluations are conducted with only factory installed components. 
This vehicle is more than capable to towing the 5,000 to 6,000 pound, 
high frontal trailer mentioned below with out any additional, 
after-market cooling components. If you have any questions feel free 
to give me a call.

Hope this helps,
