The process was easier than we expected, a bit of liquid dish soap and a helper to engage levelers while I set snap pads in place. One of the very first mods we did when getting our class A a couple of years ago, we have been 20K miles since their install and they have stayed on without issue. They are a bit pricey, but as we are getting up in years, having to to place leveling pads upon arrival and retrieve them when departing was a hassle we no longer deal with.
