Solid

I thought it was one large piece, not four small pieces that you have to build. Not hard to put together. Delivery was by Amazon, which was a day or two late. It looks solid in the truck and doesn't move around when you tighten everything together. No drilling was needed on my install "2019 F150 King Ranch." If you want something to put your tools in and not have to worry about anything falling out, then this is the product you should buy.
