I've been part of Prime since March (2019) and is my first and hopefully only VTC I'll ever be in.
It's incredibly friendly despite the many people in it and there are many things one have in common with eachothers.
There are always things to do like have a spontaneous meetup somewhere on the map, drive and before you know it, more people might have joined.
We meet up at e.g RLC, CRTZ and Tango's convoys (sorry if I left other VTC's out) which are really great, but mostly our biweekly convoys where a lot of drivers meet up to drive.
At first I didn't see the real reason to participate in convoys, but now I do and it can be very fun, especiallt among other people and not necessarily from Prime only
If you're going to apply, I am very certain you'll feel warmly welcomed by almost everyone
