I have an old school motorhome. It had an original electric steps. Their still available but for $ 1400.00 . Even the parts are
very costly. The brand is called Kwicky Lipert. I ran across the Vevor brand, all aluminum, the old one was rusty steel and very complicated parts. I bout the Vevor and installed it and it works beutifully. Its rust proof and very simple to install. Its the best value possible @ $240.00 I saved a bundle and got a better product, Vevor is the best.
