How to Install

Installing a lock box for your RV is a simple DIY project requiring basic handyman skills. You’ll need some knowledge of screws, bolts, and power tools to get the job done. While some RV owners prefer using larger self-tapping screws for added security, others recommend using lag bolts to ensure the box stays in place.

To begin, choose a suitable location on the trailer tongue for the box, depending on the size of your battery and compartment layout. Once you have selected the spot, drill holes into the metal or wood to secure the box. Fasten the lock box in place using self-tapping screws or lag bolts, ensuring it is level and secure.
