hit this guy up on IG. his link is IG:diyoverlanders
but it looks like he hasn't updated since the mid 2020's.
i dont want to take away from this persons post but there is another carpenter that can make a similar. his IG is IG:Overlanderwoodworks
i purchased my drawer system from IG:solidwoodworx - but he doesnt do custom builds anymore so you'll have to take out your cargo slider.
