Just installed this decked system last week, for work almost daily I get my hands muddy and have to use bottled water or whatever is handy. I usually keep several Powerade bottles and refill them. This decked system will have a decent cavity on both sides, wonder if any of you have an idea for like maybe some kinda bladder? And I run a hose with a valve near the rear? Some kind of “compression” bag I could rig up to refill with a hose, or if I need to run a small air compressor or water pump. I really don’t know where to look for advice but this seemed like a community to have ideas
