I just bought an 11 378 Xl T&S and they had to replace the steps. The previous owner had an extended warranty and they replaced it under warranty. I tried to tell them that they could get it done under the recall but they didn't care as the extended warranty would pay. Well that was expensive, they charged them $1598.00 for the stairs, $780 Labour, etc. and taxes to a total of $2600.00 Canadian pesos. Can you say ouch, no wonder extended warranty is so expensive. They told me they could not put in Kwikee steps as it was to much retrofitting. I checked in this morning and noticed the steps were from Kwikee. The difference was the top step was 2" more rise (not exceptable) so they moved the mounting brackets up the 2" and now it is the way it is supposed to be. The old steps had too much rise and almost touched the ground, these ones are about 1" lees rise per step so they are now about 4" from the ground. Also about 2" wider so they fill in the opening better.
