One of the guys I work with, his boss build a trailer out of stainless and went on a camping trip to France, even though it didn't have a big load on it (just his tent and some gear) the chassis of the trailer had cracked around tubes near the suspension mounts and ended up left on the side of the road as it couldn't be repaired, he had copied a mild steel version so though it would have been ok, obviously it deals with stresses in a different manner.

Sounds like weld decay, the chromium in the stainless steel reacts due to the heat of the welding process leaving a band of non-stainless steel around the weld, which then leads to cracks or corrosion. Depends which grade of stainless steel it is.
