Took my first mini road trip this last weekend and was able to take note of what was needed where. The advice of just getting out and taking notes is a great one and I would recommend anyone doing a buildup just throw everything in the Van and bring a drawing pad.
First item of need is a better bed / seat combo. Are there any other options besides:
Discount Van / Truck
FWIW, I'm looking to re create a car seat safe version of the Westfalia Weekender interior into my Chevy Express...
