I just replaced my 3 weeks ago. The biggest problem I had was the wiring harness was not long enough to plug in so I had to cut and splice in the old harness to make the plug long enough.
The switch is different, normally open for the Kwikee and normally closed for the Lippert
Unfortunately the switch that was ship with the new Kwikee steps got lost because of a torn box. I went on Amazon and bought a magnetic window switch for 7 bucks that was both a normally open and normally closed. I connected it up normally open. Works fine
Like others said steps are very heavy and need to be extended before you are able to bolt it on the MH.
Took me about an hour to bolt on plus another 30 minutes to splice the wires.
Can be done by an individual, just be sure to use 2 washer on top and bottom of the bolt for added strength.
