A. The likelihood of thieves stealing a roof tent from a vehicle is extremely low as it takes between 30-60 mins to install a roof tent correctly to roof bars mounted on your vehicle and it would take a thief a similar amount of time to remove it without getting caught. However, it is prudent to take a few precautions to secure your roof top tent. Buy lockable roof bars. These are bars that cannot be removed from the roof of your vehicle without a key. Do not keep valuables inside your roof tent. If the make and model allow, lock your tent when closed. These simple precautions will help secure your new home on wheels.
