For want of a better word I'll call the opening where the city water and TV cables a hatch. We all have a removable screw on cover that we take off when we are at the campground. My question is how do I critter proof this opening when camped? I have yet to have a problem but we are supposed to be camped in one spot at a state park for a few months this year and there are bound to be "visitors". Is there a replacement hatch cover with an opening for the hose/cable? I am looking for something similar to the door for the 30 amp cable at the rear of the Cruiser.
