Slide not staying closed

I'm all for "an ounce of prevention" even when there is no problem. I never though about my slides moving while in transit. If a little resistance like those bars offer would keep them from every moving at all in the first place, nothing would ever get broken and it would help ease the tension on the slide brakes and stops too. I think I'll experiment with those shower curtain rods I have. It sure won't hurt anything at all to experiment with it. I'm one that's 100% for safety and snugging everything up when on the road. I can add this one to my list of paranoia! And it would be very simple to cut a length of 2x4 and make one that would simply slide right in, enough to prevent possible movement! Great idea! Guess I have a new project to tinker with today.
