So, I let this thing sit for over a year, while i was gathering a few goodies and trying to mentally prepare myself up for the task at hand. And, in the last few weeks, I started making some small patch panels, and prepping for tearing into this beastly undertaking. So, I went in to work on Saturday, about 9 am, and untill nearly 8 pm worked my butt off.... actually, not quite, it's still there....I did stop for lunch. Fat people gotta eat.
First, i began with removal of most of the badly rotted sections, all of the reamaining floor, rotted outriggers, jacking points, and floor supports, and the remnants of the rear crossmember. Last, finally started welding new metal in... Replacement floor supports (the two in the rear were rotted out, under the fuel tank section), and the rear frame crossmember. I even started welding in one of the rear corners before calling it a day.... Here's some pics from it.... I particularly like the pic of the pile of rubble that i either cut off it, or that fell off of it while i was cutting something else off. Enjoy. To quote Forrest Gump, "I'm kinda tired...". It felt kinda good.

What i started with

Floor completely gone... looking pretty scary at this point
