Hi All, I have a 98 K2500 Diesel Suburban with 3:73 gearing 4x4. I was wondering if anyone else with one has problems towing 8000 lbs. give or take a few hundred pounds. No mods on the engine. Can not afford to kill the truck. According to GM I'm under my max tow weight. They list the max as 8600 lbs. Thanks for the help.
