I search everywhere for vanlife event listings to create the most complete list of van gatherings possible.
Here is my experience, and you will have to provide feedback on your own needs, but I have found none to be complete, and most of us need event listing from our mobile device, and even better, listings close to wherever we might be. Many of the event listings show only the events those builders or manufacturers are going to, and not all the other meetups and gatherings.
I also am trying to focus on Van specific meetups because gathering for RV shows, unless Vans will be there too, are a completely different type of show.
Currently I am researching the best way to know about VanLife events and so far the app called SEKR is my favorite. It has the added benefit of using your location from your smartphone to show events and much more near you. I am still trying to get in touch with someone, but I believe it is users supported, so events that show up on the app are from user input.
For those of you that want to just browse for events – Here are a couple of the more complete #VanLife event listings I have come across.
