Spends too much time on here
I have a rugged storage bin in the back of the bed and use a tiedown to keep it in place in the very back corner (closer to the cab). It is under a tri fold cover so unseen and unheard because of the tie down. Downside is it is not easy access vs. under seat storage, but good for emergency stuff or stuff you use occasionally. I keep towels, extra tie downs, blanket, etc. there. Rest of stuff you need in a pinch (flashlight, knife, battery jumpers, etc. are under the seats. Great having a truck but without a Rambox hard to keep stuff in the bed. View attachment 76590
Get a heavy duty bed mat, nothing will move around in your bed with it (you can stop strapping things down), it also protects the finish of delicate items you don't want your sand paper like bedliner damaging.
This is the one I have, best $90 I've ever spent: https://www.amazon.com/gp/product/B07MRKYQP5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
