Dan ... thanks for the heads-up on where to find your post!
I checked out the product. It looks like it's intended more for trailers, 5'ers, and truck campers.
Our little Class C already came with a built-in automatic extending/retracting step mechanism with a low electric draw switchable light for illuminating it at night. This automatic lighted step setup is probably the most used and appreciated piece of equipment in our rig!
