88 Stepside 4x4 Curb Weight

Could someone tell me the Curb Weight of a 88 Chevy 4x4 stepside 350 with auto Trans. Cant find any thing but the GVWR. Dont have access to scales at this time.

Autotrader research and compare says it weighs 4097 pounds.

The 91 is is listed at 3721 lbs curb weight by Kelly Blue book. This is the 5.7L auto 4x4.

Thanks for the help. I couldnt bring the weight up when I went to those sites .
