When people ride with you they comment how hard it is to get in.
When you have to explain to someone that the 8.8 you are swapping in has 3 more splines and disc brakes, cuz they don't understand that they are very different axles.
When your door ajar light won't go off
When your headliner is wet around the 3 brake light.
When you have to explains bumpsteer to someone.
When you drive another truck and think to yourself, wow so that's what zero bumpsteer is like.
When you can be lifted 6", run 33" tires, be as aerodynamics as a brick an still get 340 miles on a tank.
When you have to replace the fuel filler neck to pass smog.
When you see another lifted Ranger and can appreciate the fact that that person had to grind off all the same rivets you did.
