Thanks ILH, we were considering feet at each front corner underneath rather than adding the cable. Not understanding how much "extra" reinforcement there can be to the door? Is the hinge larger? That would seem to be the only area that could be stronger. Otherwise the door opening and ramp seem to be identical?
Appreciate your feedback, we stay own a spot for and stay for several months during the summer and considering how to level the ramp when open for two chairs and two people.
Thanks!
