Fleetside wood bed question

[cgster]

When I bought my truck, it came with the bedsides and the front panel, not installed on the truck. All of the bed sills are on the truck. Only thing missing is the wood and the wood strips.
My question is, will the bed stay in place on the truck without the wood installed? Just trying to free up space in my building that the bedsides are taking up. I drive it around the block on occasion, so want to make sure bed is secure. Thanks.
