Lots of room, fits perfect
I have the smaller bag that fits under the single seat in my 2015 F150 Lariat. By now I have acquired so much stuff that I needed a bigger storage bag to keep it from flying around in the truck. I got all my first aid stuff in the small bag and all my ratchet straps, my road side emergency stuff, bungee cords, and miscellaneous stuff in this bag. It fits perfectly underneath the seats. Ready to hit the road.

Good investment for any truck, trunk, or RV.
I bought this storage bag for my Tundra 07 crew max. Prior to purchasing I failed to check the clearance under the back seat. the seats were lower than I expected. The bag didn't fit. Luckily, upon moving the seats forward. I was able to fit the bag behind the seats. once I slid the seats back. I was able to conceal the bag out of sight. The bag quality is solid, the removable velcro spacers allows for more organization. I was able to stow. Rope, 3 ton flat jack, flat tool box, first aid box, flashlight, rain gear, and some rain gear. the Front pockets make for additional space for miscellaneous smaller items. the price for the quality makes it a good investment and allow for a more functional solution for limited cab space .

A bit pricey for the quality
Quality is ok but I wish it wasn’t that expensive. I also wish it came with some type of holster or velcro to stay in place for when the seat is up. If what you have inside is too light, it might move ever so slightly. But if the seat is down you’ll be completely fine.

Perfect for F-150 Supercrew
I carefully researched how to best use the ample space under the back seat in my F-150 Supercrew. I got this one and the matching smaller one from the same company. Side by side, they fit perfectly....don't make the seats any higher at all. I have been able to put so much stuff in these it's incredible! Bottled water, jumper cables, extra shoes, extra sweatshirts, umbrellas, first aid kits, emergency gear, zip ties, tool set, emergency gear, tow ropes, ratcheting tie-downs, etc.They can be easily removed for cleaning, reorganizing, etc. Some people complained that there are not sturdy, but I don't understand these comments - it's a fancy bag for organizing under-seat storage, not a deck box. There is no reason for it to be rigid like a toolbox. Bottom line - if I were to do it again, I would buy this exact combination of products!

Works perfectly
It’s awesome; it has hefty pockets that will take abuse and heavy straps to pull it. Several differently sized pockets and shapes make it very useful. I have room for jumper cables, tow straps, tie-downs, 1st aid and all the other stuff I like to keep on hand without taking up any real room in the cab. And it all stays clean and contained.

Must have
A place for everything and everything organized… A must have addition for the crew cab trucks without a storage bin …ACTUALLY…. IF YOU HAVE THE STOCK PLASTIC BIN ! You may consider removing it and using this. External pockets for small stuff, and internal storage for longer or you can make compartments with included dividers. Top zips shut for a clean look. I used for many ratchet straps, tow straps,ropes and cargo netting. I don’t anticipate carry this case, but really like the capacity and clean look.. I always with other vehicle just reached in for what I needed…but they looked sloppy..RECOMMENDED PRODUCT…
