Is it necessary to have a roof tent for the Nissan Patrol?

I am planning a road trip with my friends and we are wondering if it is worth investing in a roof tent for our Nissan Patrol. Some people say it's a must-have while others say it's not necessary. We are looking for some advice.

In my opinion, a roof tent is definitely worth it for a road trip with friends. It adds an extra level of comfort and convenience without taking up any space inside the car.
