I was at a dealer last week and happily discovered I could set up and take down the Trailmanor by myself! So now I am looking for one. However, as a single female, I have a couple of questions: (yes I am probably a paranoid city girl!)

1. When the trailer is open, is there a way to secure the slideouts from the inside? I realized that when you closed the trailer, all I did was step under the slideout and pushed in. What is to prevent people from doing this while the trailer is set up and you are away from it?
2. Are there gauges to keep track of the water, propane, tanks, etc. and if so, where are they located?

Thanks for your help. I have learned a lot from this forum.
