the latest edition of Custom Utes & Vans has some interior designs (out last week), mainly for the front of utes, but can be adapted to also match rear of vans... also just go to google images and type interiors and see what comes up.... or just go to various van websites and sticky beak at photos.... don't limit yrself to panel van views either, you can pinch a heap of ideas from any vehicle website showing mods like hot rods, s/machines etc.... sometimes all it takes is one little idea that you can then extrapolate on.... good luck
