Towing, again

["Garfield" <garfield@northamericanmotoring.com>]

I need a Chevy expert:
A salesman is telling me he has a '98 Chevy Silverado Z71 with Tow Pkg in
Maroon/Silver with the 5.7 V8.
I've done a Carfax on the serial number and it reads as a "K1500 Club Cab,
5.7L V8 SFI VORTECOHV, 4 Wheel Drive"
The problem is, I can't seem to find a tow rating on this designation.  I
can find a C1500 with the 5.7 but the K1500 4wd's are only listed as 4.3V6
or 5.0V8.
Am I missing something?
