Training with your gear is critical, otherwise you are just carrying around dead weight because it’s useless if you don’t know how to use it right?
One of my favorite articles from The Prepared is this one about bugging out to your back yard. (I bookmarked it because I like it so much) Such a simple but effective concept that I haven’t seen any other preppers talking about. You should read it because it answers your questions pretty well.
Part of testing out your gear is knowing it’s limits, seeing signs of wear, how to repair that gear, and maintenance that you will need to do on it. Taking your BOB camping once isn’t going to be a realistic scenario, wear your gear out and learn how to take care of it and learn when you need to replace it.
That’s the respectful and fun way to treat your BOB. By using and testing it. I feel bad for all those bags that have sat untouched on a shelf for the past 20 years.
