My friend thinks he can tow me backwards in his chevy 1500 with a 5.3l. My truck is a 1988 gmc sierra 3500 with a 5.7l v8. Can my truck pull more than his and if we do decide to hook on to each other who will win. Also i have 255/70/16 tires and his are 285/70/16. Both trucks have 270000 kms and 2 inch body lift. Mines a single cab long box and hes got an extended cab.
