67-72 C30 for pulling a 3 car wedge

[olschool]

Hi All, was curious has any one used a 67-72 C30 to pull a 2 or 3 car wedge trailer 5th wheel design. I know that the C30 has a 10,000 gvwr along with a 3 car wedge with a 15,000 gvwr keeps the combine gvwr under the 26,000 lbs (no need for a cdl license) I know the 67-72 C&C rear end is narrower than todays 1 ton chassis. Thanks for any info Dwayne
