Welcome NoloJS
You came to the right place.
There are more opinions, ideas and good advice on this site then you would need to build a million trucks.
Some users concentrate on achieveing the perfect expo look, others are all about hard core off road utility and still other achieve both.
Heres the starting point for all my serious builds.
1) Find a hill where you can roll a similar truck at least 5 revolutions.
2) Strap yourself in good and tight.
3) Roll that truck off that hill.
4) Now, build your truck based on the information you just collected.
This simple experiment will perfectly define the parameters of your build.
Most people rely on the assumption of invincibility when deciding what/ how to modify their trucks.
Think about a flight simulator. Its really nothing more than a safe place to practice all the different ways you can crash.
Safety First is not just an overused motto, its paramount.
The first thing you are prolly gonna notice is that the cab will decompose. That will scare the living POOP out of you. The sound will be deafening. The glass, dirt, rocks, stuff from inside the cab will slam into your face. So how do you address this? You build a cage. Not bolt together a cage that gets shipped from China in a 3'x2' box, but a cage so intricate and complex its a PITA to climb through. Thats if you value your skull, spinal cord and the rest of the crap thats close to the steering column.
The second thing you are prolly gonna notice is the rib pain. There is just something magical about how quickly and easily your ribs will bruise and/ or break. So that means ull be interested in getting a really supportive seat.
The third thing you are prolly gonna notice is the throbbing pain across your chest from the unpadded shoulder belt. Thats a sign from God almighty that you should think about a really good 5 point harness.
Imagine you are in a blender...
Oh no, I feel ive said too much.
Anyways, welcome to the site and i look forward to following your build.
