A few suggestions for your panel van which looks suspiciously like a GMC G15.

modification : dividing the texture maps for "glass", "hull" and "metal" for more possibilities

add-on :  back row seats.

new version : how about a minibus ? 

Trivia I found somewhere : the early A-Team van had a red "GMC" logo on the front, which was taped over later on as GMC didn't  want to be connected to the series anymore.  Something about "poor quality of scenario's".
