i am in the process of building a 6 pack rack ne one oes this before... i am making it out of steel which cost me $7.01 and the rack if u buy its like 70 +... im using 2 in angle iron for the frame and taking 1 in by 3/8 in steel and puttion strips on the bottom.. and then im making brackts so i can just mount it on the my grab bar..and then be able to take it off when i dont need it. if ne one else has done this i am wanting suggestions...and if ne one is interested i can try to write up plans.. and waht u will need

 

I have one of those $70 six pack racks and love it. Even when not carrying cold ones, I can use it for a trunk.

Good luck making one.
