This is a common problem I've observed in my RV storage lot, and unfortunately happened to me last year. I found the nest while hooking up for a trip I had to make. I've since put a barrier (wire mesh) up which will prevent that from ever happening again. Unless you can successfully relocate the nest (and simply moving it will most likely cause the parents to just abandon it), you will have a difficult choice to make.
