I've been looking for a bladder-type solution for quietly carrying water inside the vehicle and trying to do so in a space efficient way that also is easy to access. Especially for those of you with drawer systems, I have found a low-tech solution that is brand new to the market. These were developed for motorcycles and are super rugged, check out the videos on YouTube of guys running them over with big dual-sports bikes.

I have always struggled to get the best utility out of the wheel well wings but now with the driver side holding my aux battery and now the passenger side carrying two 3gal water bladders in a great location for accessing the water I feel like I'm really dialing things in.
The perfect solution for me meets these criteria:
Lightweight
HD construction
No noise of sloshing
Not mounted on the outside
Perfectly fits existing storage
Portable btwn vehicles
Keeps the weight low
Can dispense easily
Light enough for the wife to carry
Takes up little space when empty
Some practical ideas that this setup allows that only came to me after purchasing:
Smaller multiple jugs mean you will have an empty one regularly enough that you don't have to lug a half-full jug to a location to fill.
Multiple jugs also give you the ability to use these as containers for a gravity filtration system.
They roll up so discretely that you could take them into any establishment and fill them in the restroom sink.
I will admit the cost is on the high side for sure but I just haven't found any other solution that works as well as this for this use case so I thought I'd share.
