I like this project a lot - and not only because I'm a "van man" myself - my first car was the "square" VW bus, and my second car is a fourth generation VW bus - I have owned it for 20 years now, let's see if I can make it more...
This project is so cool because you are modelling something you know very well - and many modellers miss the fact that knowing your subject well is the foundation for a good model - much more than fancy paints, airbrush skill or tons of aftermarket.
Good luck with your build and have a nice day
