I got these standard size organizers to go inside my Thule Alpine roofbox and they fit perfectly. The lids will ensure nothing falls out on bumpy roads and the organizers even have straps on both sides, so I was able to secure them to the hooks inside my roofbox so the don't move around. I also noticed the velcro on the bottom in case I want to put them in my trunk. I'm very impressed with the thoughtfulness of the design and the quality of the materials. I recommend this product for either your truck or even Thule roofbox.

I like the product. You can arrange compartment sizes. The max # is 6 and you can remove separators to have 5, 4, or 3 compartments. It's well made.
It didn't come with the straps to latch in on the sides but I've been able to substitute bungie cords to do a similar function. It still kind of bugs me. I didn't want to send it back, it was enough to unpack it, didn't want to pack it again. Plus, the clasps are a standard size so if I put some effort in I can find straps to fit.
You'll likely have better luck.
It is soft so if you are planning to put cat carriers on top (or something like that) you'll want to put a piece of pressed board on top or underneath the lid. Easy fix.
I need something this exact size to stretch over one side of the back seat and also over another organizer on the floor boards to get a perfect cat perch where they can see out the windows.
It's really made for a car trunk but I had a different aim and it fits my needs.
I store cat belongings in the organizer when we travel and car emergency aids in the lower one.
The whole setup only takes up a third of the back seat while providing a large amount of storage. So I don't need to remove it from the car at all. There's plenty of room for groceries or two passengers.

With my new vehicle (Toyota RAV4), I wanted to add a few things to make it more personable. I been using my trunk a lot for random things and didn't want to keep tossing them around. I purchased this product and it is a great fit for me!

It comes with barriers to make the sections as big as you please. It is very sturdy overall and has a lot of space. The pockets are a nice touch and this thing also comes with hooks to attach if your car comes with any already to prevent it from sliding around. I use this to add all my miscellaneous products just to make it look more presentable and organized. I do recommend a product like this as you can't go wrong to being more organized!

I like the ease of folding if I ever need that. I just keep it open with the divider to make 3 sections. The very bottom of it is just material. You get an insert for the bottom the is the material with cardboard inside. You insert that for the bottom of course...lol.

Versatility is good for me. My hatchback car has a few places to connect the 2 holding straps that come with it. I use 2 straps connected to right side at rear of car. Otherwise using 2 straps (right side and left side) centers it and makes smaller gaps on the sides of it to put more stuff if needed. Works fine on one side of car.

The cover with Velcro is just that - a cover with cardboard inserts. Daisy chaining more of them is a nice feature but, I don't need that feature as of yet. Other similar items have handles that extend above by about 2 inches which makes it inconvenient to stack things on those products. You can stack on top of this one because the box height is the same and the privacy/dust cover helps with having a flat surface to stack on.

It's now easy to organize stuff I want in my car - frequent used/emergency items in this container while roadside emergency/car maintenance items in a mechanics bag I had. Sturdiness seems ok for now. I will see how long the cardboard holds up. I cover it up with a moving blanket I had to protect it from dust, dirt, and the zooming radiation that comes from our Sun. I got a lighting deal so cost (value) is better for me which matches the cost of other brands.

It's new and protected so I don't need to clean it - ðŸ‘.

Consider this one to purchase, but I would get the larger ones if I had a bigger car.

I had an old one of these from Target and was expecting pretty much the same. I'm very pleasantly surprised at the quality of this. It's so much nicer than my old one. It's very sturdy and holds it shape. I love the extra pockets on the outside. I chose the grey and it's very pretty. I also love that it comes with a top (which is optional) You don't have to put it on if you don't want. Impressed with the quality. Makes my trunk very neat.
