Okay, I'm sort of bored too so I'll mention a few. Now remember, my X is only a 4x2, so my mods are mainly cosmetic. Anyway, I have the Sgt. Lobo shelf mod that's probably my favorite, CB and antenna install using an ARB mount on my rack, cell phone/GPS/CB mic holders in various places, removed my mud flaps and step rails (no money cost there), bought 31x10.50x15 tires, rubber stubby antenna (another favorite as weird as it sounds), cheapy off road lights I bolted on my bumper (mainly for night fishing and kayaking purposes), pocket mod (cheap mini-mod that's pretty functional using pockets I've cut out of old cargo shorts), red map lights (for work purposes at night so I'm not blinded by the super bright regular map lights), AA maglite holder, visor organizer (just a cheap something to hold documents, air gauge, and other small things), Rubbermaid cargo box (not considered a mod, but it was cheap and it has saved my cargo area more than once), roof top cargo bag (again, not a mod, but something I keep in my cargo area that has made life easier), and that's about it. Looking at getting other sort of unimportant things like a marine gas tank to put in my gear basket, Thor mod, DVD player and monitor for my kids during long trips, and who knows what else. If my X was 4WD, I would focus more on performance mods, however considering I mainly stay on pavement about 90% of the time, I thought I would stick with things that would benefit me personally.
Of course, I have a LOT of little things I keep in my X too that aren't considered mods, but more like "just encase/incase/in-case" items and camping gear.
