Do you tow on flat ground only? A half ton, non Vortec motor Burban will suck to tow with. You can buy a 4x4 late 90s tahoe or suburban for like $2000. I have a 2004 1/2 ton Z71 Chevy and I will never tow a rig to the rubicon with it again. Overheated the tranny and smoked the brakes. There is a reason tow rigs are 3/4 and 1 ton
