I haven't taken the plunge to put windows in yet. still sitting on the fence, but rest of van conversion is almost done. no water or cooking, just a nice and cozy spot to sleep and hang out for 2. double hinged bed bottom allows for easy making of bed while still getting at the storage under the bed. separate smaller box with hinged lid toward front is part of bed but allows for some sitting flexibility. 1X2 piece of wood to support the bed on passenger side easily removes when bed is up. flip down table hides stuff and allows for a nice place to play cards or eat. I tried really hard to keep the weight down and stayed with 3/8 baltic birch plywood for most items, even thinner for over head cupboard. bed surface is 5/8 standard plywood.
