i used my 1970 chevy CST-10 as a hauler once.... big mistake sorry to say but usein a 1/2 ton coil truck to pull a car trailer with a fullsize truck on it is not a good idea.... but then again it didn't help that my frame was rotted out above the coils (didn't know that till after) but ya needless to say after hauling my 68 IH 1100C my frame was a little bent... the rear bumper was like 1 1/2 feet off the ground with nothing on it.....
