Hi! I wanted to share a bit about this van I've built, it has been great for travelling and camping around the west coast, primarily through the winter for snowboarding. The van is now SOLD.

I would also consider selling the entire interior buildout and installing it in your (2nd gen) Sienna!

FAQ (as a work in progress):

Q: What are the bed dimensions?
A: The bed is 76" long and 46" wide, the L section of the worktop and the drawer fridge overhangs the one side of the bed a bit, making that side a little shorter. I haven't actually measured how much. I'm 6' so I sleep on the full length side as the shorter side is just a bit too short for me.
