I use the same security for my power cabe that came from Camping World not a very secure system. But there is no secure system, if they want it they will take it. Most of my stays are in RV parks and in 6 years of use and about 8 month a year travel I have never had a issue. I very seldom lock any storage doors. Much cheaper to replace stolen things that to replace storage doors and all storage and RV doors isn't strong at all, 6" screw driver will in seconds open any RV doors.. When we had our wonderful Montana (furr kid) I never ever locked the entrance door in case there was a fire someone I hope would let him out. As most know Locks only keep honest people honest... Happy Trails....
