I depends on what you are looking at getting out of YouTube.
I personally am looking at using YouTube to show my vehicle build and passing on videos of my trips to friends. I may even look at doing a couple of reviews if I purchase something out of the norm. This does not mean you can not make it look professional.
I am not looking at making any money out of YouTube or advertising. Some of my colleagues say you should do this or that. Which I think will take the fun out of the experience of Overlanding and more time editing videos. If in time the channel becomes big enough I may reevaluate the YouTube channel, but for now it is there for fun.
Now for the shameless plug
