After fitting everything we stripped it all back down to the frame for sandblasting. Shown here hooked up for the 50 mile trip to the blaster. Even pulled the inside rims off for access to everything. All surfaces are cleaned down to bare metal before painting.
I try to avoid two flat surfaces of metal contacting each other,unless I enclose it with welds. Your not able to paint these surfaces,which in our enviroment is guaranteed to rust out. In the case of the two I-beams stacked and the heavy top flange added, I didn't want continious welds running the full length of the frame. So we ran welds every 6" or so,then filled the seam with a paintable silicone after the sandblasting was done. This has been working well for us.

nice work!
I have a question, how much trouble do you have with cracking on the cross bracing welds? I imagine there are some tricks involved with allowing the frame to flex and twist without the braces fatiguing and cracking???
