From the sound of things, I'd guess Kwikee does nothing about re-engineering their step to prevent future occurrences of this failure. I may be wrong. People with these failures need to report them to LTV. If enough dissatisfied customers do this, perhaps LTV will look at other step options.Actually this is directly between my dealer and Kwikee - LTV isn't involved at all. This was covered under the two year warranty on the steps.
That said this is apparently not an isolated event by any means given the number of folks who have chimed in since I started this thread. The pictures of the failed step linkage that I posted here were also sent to Kwikee and they understood the nature of the failure right away. Kwikee's reaction tells me they have seen their product fail this way before and probably more than once.
