The first thing you need to do is get the information and maps for your area.
The next thing is study them and pick a route.
The next thing is fill up with gas and take a drive.
Your stock truck will go 95% of the places your able to drive in most states. With some more aggressive tires snd some experience. You are now going 97% of the places.
The other 3 % of places need a bit of modification. And 90% of those places are illegal to go to in most states.
Go find a campsite and spend the night. It takes very little equipment to overland.
Now to make cool you tube videos...the list is endless.
A map, a reservation, food, water, shelter, a toilet of sorts(or shovel), cooking mechanism, and some gas and the adventure begins.
And adventure is necessary.
