OK. Here is what I learned so far. Yes Kwikee was bought by Actuant. The customer service function is now non-existent. However, Kwikee seems to be the vendor most rv mfgs. use and there seems to be very little problems. They only have a triple step, no quad, but there are 2 versions. I will need to print out the specs and check to see if either are long enough.
The other company is Stromberg-Carlson(yes, a Lippert company). That brand doesn't seem to be too popular, haven't found any comments on them one way or another.
I am going to "ask the factory" about the possibility of electric steps with 4 steps. I will also contact Master Tech in Elkhart to see if they have a solution.
Any step you replace will mount differently than the one you have. That is a given unless you luck out and find the exact same step(ha!!).
Will keep you updated on my hunt.
May end up going with a 3 step plus a manual step(really don't want that), or, see if I can mount a bottom flip up step(manual) and still close the 3 step.
