Fans of GTA 5 and GTA Online might have heard of the Sandking or the Sandking XL which is actually a huge truck that was originally featured in Vice City.
The truck is pretty expensive and can usually be bought from the browser for thousands of in game dollars.
However, there is a video on YouTube where the player shows a way through which you will be able to find the modded Sandking XL in the game.
As you can see above, the short video (Courtesy Console Gamer) shows you a special spot on the map where you can get your hands on it. The truck costs approximately $17,000.
However, you will have to follow specific instructions, even the given time at which the Sandking XL spawns on the given location.
So yeah, this is a pretty good way to get your hands on something expensive for free. That being said, do try and get your hands on the yellow one as it sells for around $18,000.
Do keep in mind that this thing only works in the PlayStation 4 or Xbox One version of the game; so you better be playing it on either one of those if you are looking for some freebies.
