Initial thoughts...
-make inside skirting a darker color so we don't attract attention to it.
-make inside skirting in 4-foot lengths (module size) this will make it easier to access stuff stored under the modules.
-use velcro to attach, but put the velcro on the back side of the facia. Skirt would hang from underneath the module.(interferance with wire harness?)
With the skirting just as long as the individual modules it will be much easier to adjust to make room for C-clamps, etc.
I am a fan of the inside skirting idea but I would say if it is approved it needs to be put on the list of to-do items and done based on order of importance.
