Perfect use of time, while you are traveling down the road? VanLife Podcasts.
I was surprised by how many of these I was able to find. There are podcasts that relate to VanLife, like RV and BoonDocking Podcasts. Each of these has many episodes you can listen to when you find the ones you like, and you can subscribe to them.
Next time you are bored on the road, or at your site, load some of these up and increase you knowledge at the same time. Man, I wish these would have been available when I started doing this years ago!
