It is a closed cell board which repels moisture, and the install is becoming more secure than I had initially thought. I've been considering how to make it more permanent so that I could tow without removing it, and a cable system is one of the things that I've thought of as well. I would have to upgrade the angles and hooks for that though. I may also add two rows of lengthwise furring strips, sandwiched between the 1/4" line and the insulation, to add additional support.
