Is this the start of the slippery slope where your "Expo" rig turns into a Crawler?!?! haha The hunt for the ultimate do-everything vehicle is a path I'm all too familiar with.

On the White Rim
Weeeeeell... I hope not. I want to be able to do what ever I'd like to with my rig. Right now, I have it outfitted pretty well for 90% of what I want to do with it. My build is pretty straight forward:
2008 TT, a/t., APR X-1, 285 KM2's, with Toytech/TT Bilstien adjustable front shock kit, LR upper arms, MetalTech LT rear system with reg. springs and 1.5" spacers, stock rack with WAG basket, Fab Fours bumper with Warn 9.5ti, 15 gal Dale's aux tank, drawer system with slide out work table, this has three interior config's for sleeping inside and rear seats in or out, dual-battery system w/solar, ARB compact compressor, ARB fridge, All-Pro DoM sliders, BudBuilt skids and diff skid. So nothing too fancy.
I want to be able to put 35's (or something close), on steel wheels as an alternate "mode", and I want to be able to switch back to the 285's for overlanding and towing (I hope to get a Bambi someday). So that means re-gearing. I'll probably go with 4.80somethings. I would also like to get a two-speed Atlas for "crawl". I'm also going to have to get stiffer springs for the rear and hopefully lose the spacers and some sort of longer travel shock in the front - I think that I can gain about 1.5" which along with a 1" diff-drop and the BMC and some wheel-well modification should help fit larger tires.
I don't think that any of this will inhibit my overlanding abilities at all, I wouldn't want to since that is the ESCAPOD's primary purpose. I like it so well that when I've driven the wheels off of it, I'm going to put them back on and when the motor dies, I'll put something else in it. At least that's my thinking right now.
