Floor Pan Steel Thickness

[rustomatic]

Okay, folks. I'm nearly done with re-creating the middle (and ends) of my Falcon, and I need a bit of advice on sheetmetal (since I finally quit law school, I'll have so much more time now). I will be adding a bit more tubing to both the tunnel area (to add torsion-fighting structure) and the floor, along with cross bracing at seat and foot areas. (The current cage structure is coming out.)

I was thinking 16 gauge, but now I'm leaning more toward 18, since there will be so much structure underneath. I'll probably definitely use 16 for the front and rear firewalls, but for the floor, it seems a bit much.

I'll happily accept any suggestions here.
