I saw a few posts a LONG time back about people modifying their LS's rear locker to shove some fat sac's in there, but nothing recently. My gas tank is located directly below the rear locker, so I really do not want to put any type of significant weight in there for fear of damaging it.

My question is this: has anyone built some sort of platform to support a fat sac (I am planning on putting #300-#500 in there)? I was thinking that 2x4's and 5/8" plywood would provide sufficient support and would distribute the weight evenly across the tank and stringers.
