This is an ADD-ON to the 4 mounts (2 mounts per side) for your Pak Rax. This will allow you to stack another RotoPax can to one side which will allow for a maximum of 16 gallons of gas held on the Pak Rax. This is the most fuel you carry at an easy access point for the Jeep Wrangler.
“New Anodized Aluminum.
Finally, you can stack multiple packs together! Use in conjunction with a pack mount (RX-PM, RX-PM-DLX, RX-PM-LOX).”
