What is the best way to maintain the off-road capabilities of a Nissan Patrol?

I recently purchased a Nissan Patrol and I want to make sure it stays in top condition for off-roading adventures. I've heard mixed opinions on what the best maintenance routine is. Can anyone offer some personal advice?

Regularly check and replace the air filter to prevent dirt and debris from impacting engine performance.

Don't forget to regularly check and top off all fluid levels, including oil, coolant, and transmission fluid.

Keep an eye on the tire pressure and tread depth to ensure optimal handling and traction on rough terrain. And don't forget to rotate the tires regularly.
