VW T1 Camper

I am thinking currently of building a camping car based on the VW T1, something like this:

There two ways that came across my mind: either to fill some windows of a Revell or Hasegawa Samba bus, or to start with a van and open the missing windows.

I prefer the first approach. However, I'd like to consult the experience of the styrene experts out here.

I've been building a '56 Kombi from the Hasegawa Type 2 Micro Bus (1963) ’23-Window and would have to say just fill the windows. I used sheet plastic to fill then body putty to fill in the seams. The curved rear ones I used a few layers of thinner sheet so it bent around the curve. I have a thread on the build where you can see some of the window work on another forum. (http://www.modelcarsmag.com/forums/index.php?showtopic=25095&hl=) Just follow the link. At least by filling windows you don't need to measure and figure out where the ones you need belong or create the trim molding.

I also have a 85 GMC Van on the table (http://www.modelcarsmag.com/forums/index.php?showtopic=35282&st=0&gopid=360049&#entry360049) that I did cut out the side windows for and there's a shot or two in the process. This wasn't too bad and I only needed trim for 3 of the windows.

To tell the truth, both were probably equal work. It may just come down to which way you feel most comfortable with.
