After pondering the possibilities for a limited budget transformation of my apartment life for the remembered freedom of on the road; I bought a 2002 Chevy Express 2500 cargo van a few days ago. I am pleased with the potential. Slightly daunted by the initial steps that I consider essential...I need a couple of windows added at least to the side, barn doors. Thinking of 2 roof vents, skylights for more daylight and ventilation. And I need to install a third seat as I have two young grandsons who will with some frequency travel with me. I am imaging a swivel seat that could become a comfy chair when parked. Then the rest of the build out feels strainght forward. Any opinions on these two pressing issues?
