MORryde Step Above Steps

I stayed at an RV park last year that is designed for over night quick in and out and was great, but the sites were level where the tires are, but sloped up almost immediately to the level of the adjacent row of sites. I saw it reported one time that this step mod would work as long as you had level ground out to as far as your extended slide on that side, but in the case described this wasn't the case. If the ground slopes up almost immediately from the tires it will clear the bottom of the slide, but I just don't see how this step would ever work regardless of the position of the adjustable feet. I know it would not work on the site I'm describing.
