04 Titan 4x2 Off Road Package Question
 

I bought an 04 4X2 with the off road package. I plan on going to a beach on the southern end of the Outer Banks this summer. There are no roads and recommend for 4X4 vehicles. I think I'll be fine on the beach. Plan on lowering tire pressure to around 20 psi. Any suggestions? What does the Off Road package offer me?
