Heh, Breeze what have you already got mounted on the rail that you couldn't fit the propane locker. Port side on our boat we have a MOB pole and a life ring mounted on the far corner and a Magma BBQ mounted on the top rail, the starboard side holds our lifesling, the two (2) GPS antennas and the mount for our dinghy outboard. I mounted the LPG locker below the BBQ and still had clearance for the portside swim platform locker to open to the max. I can send you a pix of the locker in a few days if you can wait.
