Check out this optional Porcupine Support System for under-bed toolbox mounting on your RV hauler or CANBed build! Gregg shows how the Porcupine Support System fits into the 48" wide space, allowing a 40" wide x 8" tall x 2' deep (or 24", 36", 14") pre-manufactured storage box to bolt up flush from underneath. Use our templates to pre-drill, install the supports inside the frame with 4 downward bolts each, then jack the box up and secure with 8 strong bolts from inside – super secure and easy! The Porcupine Support System is perfect for adding locked storage without losing bed space for toys/vehicles. Available for purchase on rvhaulerstore.com – add it to your DIY CANBed or let us build it in the yard. Customers buy boxes themselves or ask us! Ready for your Porcupine Support System upgrade?
