You will see from my avatar that I run an A class RV. Following the current thread on motorhome security , straps on doors, the issues are different with an RV. With only one entry door which has two locks , one being a deadlock, forced entry would probably be difficult. I do question security on the sliding windows , they appear to be relatively easy to force open, their main protection being that they are about 6ft from the ground and you would need a ladder to get in. Does anyone know of any RV break ins and preventative measures ?
