After having MH's for years with the Kwikee electric steps, we love the FW with the MorRyde steps. The pros definitely outweigh the cons and the cons aren't really cons but rather a different way to to deal with them.
The good; super stable, easy to deploy and stow, no electric parts to fail, adjustable.
Things to consider; They do pull dirt into the RV unless you brush them off first, you need enough distance between you and something next to you in order to deploy them. In 6 mos of ownership this has really only been an issue at a storage lot and I have some control over that.
In short, we love them and wouldn't trade them for the old style for anything.
