It took awhile to get to this item, but last night I rough cut and put hooks on the piece that will become my desk in the truck. The desk board is about 21″ x 12″. I found a couple of (3/4″?) conduit hooks made quick and easy hooks to go over the top edge of the glove box and were thin enough to allow the glove box door to still close easily. It isn’t real pretty, but it is super quick to place and use.
The hooks are not enough to hold up the desk with the weight of the laptop. I’ll add a cord or small rope with a hook to the passenger side grab handle to support the right rear corner. The plywood is at least 1/2″ thick and is sufficiently rigid that one support cord will be enough.
