Hi rsimoes,

What I've been told (trying to keep the kit mfrs name out of this because I don't have their permission to use it) is that some SS chassis were made similar to mild steel in both dimensions and welding techniques, and were shown to develop fatigue cracks in commercial service much sooner than comparable mild steel ones.

Research showed this Canadian commercial vehicle mfr finally used an SS material different from 304L, 312L and the like, and over the last ten years their frames did not corrode in heavy winter salt usage, and did not develop fatigue problems as had their earlier efforts in SS.

For short-term use this would not really matter. For those of us who use the cars on the street for many years in all conditions and many tens of thousands of miles, it could be safer.
