A new photo in our album shows our camping kitty Paige with a homemade Velcro attach point for a cable tie. The Velcro ties were placed underneath the trailer and in the electrical compartment to secure wires to metal without drilling holes. I used 2" squares of Lexan plastic, but any flat material should work. The industrial strength Velcro I found at Home Depot and a flat head machine screw is countersunk under the Velcro. The cable ties are the type that have a hole in one end for screw attachment. This method of securing wires and cables is strong enough and the Velcro can be removed if necessary.
Paige was very sleepy but willing to pose for the photo.
