Badlands Club

I got my first Bronco a couple weeks ago (bare with me as I immerse myself in this new language)... a '22 BL 4d HT, running 33s. Did I forget an important detail in my stats? Anyway, the first thing I have to say is that I am fantastically in love with it, particularly so after taking it to the ranch this past weekend. Nothing major, just Central Texas hills and valleys. It handled like a dream. That being said, I do want to make it mine. I know that the world is an oyster when it comes to mods for our ponies, and frankly, it is a bit overwhelming to know exactly where to start (since I do have a limiting wallet). I've been reading through so many threads and blogs that I've probably scrambled my brain, but I think I've decided where is best for me at this time and thought it wise to ask the experts, aka Fellow BL Owners, for some guidance.
As far as BLs go, what is most popular/effective for paint protection against scratches and rocks being thrown up when out in the elements? Do y'all find that the films get it done? Are mudflaps handy or something else more sturdy or effective? Also, what is up with the sound system?!? I mean, I know I didn't buy it for that, but sheesh... it's so...flat. So that's where I'm starting... paint protection and improving sound (on a budget). After those two, I guess it's time to look into air intakes and exhaust systems, then to personalize with splashes of color with some graphics. Is it just me, or is it WAYYYY to easy to become addicted and need EVERYTHING to have the bronco logo/horse on it???
Experiences, Thoughts and Opinions are very much appreciated. Pics too!!!
