Thanks for the kind words, y'all. Eric, I appreciate the suggestion, but I'd already bought a heap o' screws to weld to the chassis.
So I may be done with the metal fabrication at this point, aside from final welding/brazing and cleaning up the bigger globs.

I decided it was time to focus on what has been a pretty daunting task looming over me....the interior. And once I decided to cut off the roof, it put more pressure on me because the interior would be so visible. I've never done an interior so it was a bit intimidating to me. Well, time to "jump into the fire!" James Hetfield would be proud! :ror:
I decided the interior would be styrene over a metal base. First I built a shroud over the t-case as a basis to build on top of.
Then I welded a plate across the rear framerails that I could eventually screw styrene to.
Add some wings to serve double duty. They provide a nice, wide base for the cab floor, but they also will help support the batteries which will reside under each wing. These will come in handy particularly when the rig is upside down. ;-)
Trimmed out some floor templates for the cab and bed that will help me accurately cut the styrene later. That big hole in the middle has a distinct purpose.
The fuel cell covers the hole and the ESC will be mounted inside with the wires underneath out of sight. I think it should work out pretty nicely...I hope!!
The floor will end up being a tad higher that I wanted in the footwell area, but I think it's a small price to pay to have the batteries where they are located, i.e. low and fairly far forward. I actually ended up having enough room to fit my 3s batteries in there, too. Not that I would EVER consider an idea as silly as running 6s or anything. 8)
Oh, I got my RC4WD hubs in the mail. There's no tool to screw them on so I screwed them on top of the wheel lock nuts. Fortunately, there was plenty of thread available. They stick out a little far, but they look better than the exposed threads and lock nut!

You can see the rear hub in the last pic. I'll get more tonight...
