Name's Ray. Been a member on GMTNation since I bought my 2006 Chevy Trailblazer LS w/4x4 and the G80 Auto-locker back in April this year.
She's got 155ish thousand miles, and right now is our family's ONLY vehicle and daily driver, so I have to be super careful. :/
I have always liked the idea of off-roading, but frankly, before today, never went 'for reals'.. I bet my trip today wouldn't even count as 'for real offroading' by many of your standards, but it was a BLAST and I think I pushed my 99% stocker truck to its - and mine as a novice wheeler's - limit.
I have a few mods on my truck, mostly appearance and a couple functional (that look good too) mods:
Exhaust resonator delete;
Roof rack delete;
Pinstripe delete;
Badging and rear bowtie delete;
Blacked out stock wheels and grille crossmember;
LED side markers, flashers (A/O/W switchbacks), and license plate lights;
LED interior dome, cargo, and 'reading' lights;
Philips Xenon HID Low-beams;
Quad-hi beams / DRL kill.
Unfortunately, aside from the resonator delete, no 'real' offroading mods like a lift kit, body lift, wheels/tires, spare remount, light bars galore, auxiliary equipment (hi-lift jack, spare parts cabinet, offroading essentials) etc.
All those will come as I have the $$ and time, and only after some general insurance/maintenance type things happen (shift/servo kit, flex trans cooler lines, auxiliary trans cooler, performance rotors and ceramic pads, and possibly a valve job and/or valve cover gasket).
I will post another topic under the 'Trail rides' section complete with pics and write-up about my trip today. Like I said, it was real fun and I learned A LOT.

Anyway, I hope to be an asset here as well as learn a lot about this new, fantasmagorical world of driving offroad.
Until I get my other topic about my trip up, here is a couple pics of my 'rig' (if one could even call it that at this point..) about as twisted up as she'll get with one wheel off the ground. Enjoy!
