Those first scratches are the worst. Especially on a new truck. Don't let this experience discourage you though. In my opinion, the views you see are worth them. Depending on the trails you ride, unless you are out on a prairie or in the desert, which even then... scratches are going to occur. It's just part of it. Some tracks are wide enough, on highly traveled routes, where you can pass with ease. However, the further you venture out, the less traveled the roads become, and sometimes nature begins to reclaim the trail.
I've seen a lot of good suggestions on here if scratches are an issue. Might I suggest also, carrying a good machete or bow saw in your rig, in case you come across some big stuff. Also, there are some good videos on YouTube about trail etiquette, and tutorials for driving off road and dealing with different situations you may encounter. For me, I think scratch add character. Like was said before, there's a story behind them.
