Beyonce & Jay Z -- Ride or Die in Bed Of a Pickup Truck! (PHOTO)

Surfboards, pineapples, giant bags of weed ... and Jay Z and Beyonce -- all things you typically find in the back of a pickup truck tooling around Hawaii.

The Carters are on one of the islands for what's supposed to be a secret getaway, but there's NOTHING inconspicuous about two of the world's most popular entertainers riding in the bed of a pickup, right? By the way, it's totally legal in Hawaii.

Jay spotted the photog riding behind the truck ... and threw up a "Hang Loose."

Maybachs look way different in the islands.
