Pretty practical and the best of both worlds. You can fill up Jerry Cans anywhere, but with a built in tank, I'll need a water hose.The people I bought my camper from used jerry cans but tied them into the water system on their replacement camper.

Yup, those are photo of our water system when I was making it. We were super happy with the jerry can setup (5 were under a dinette seat like in the photo, and the 6th lived under the kitchen sink in a holder). It's super easy to pop one or two out, fill them at a garden hose, a spigot at a gas station, a spigot at a ranger station, a fresh stream, or transfer water from another truck. It also makes giving water to another overlander easier. Once in Alaska, a super helpful ranger took several of those cans to his living area, filled them for us, and brought them back to us a little while later. Super convenient. The truck has full water filtration, so the jerry cans made getting fresh stream water way easier than if we had used an integrated tank (no need for fill hoses and pumps). In my option, for long duration overland travel, this type of setup is way more practical than an integrated tank. You can also store them in different places in your rig to help optimize your weight distribution. Having individual jerry cans made it easy to track water use, and super easy to dump the water and clean the tanks whenever needed. Cleaning jerry cans is super easy; draining and cleaning integrated RV style tanks is a pain in the neck. I totally recommend doing it this way.The people I bought my camper from used jerry cans but tied them into the water system on their replacement camper.

Thanks for the great tips! I love advice from pro-expedition folks, especially those with the ultimate 4x4, a Unimog.Yup, those are photo of our water system when I was making it.

The little white couplers are non-corroding medical grade (plastic and stainless steel) quick disconnects that seal off when you unplug them. The disconnects that I got were two directional (single direction quick disconnects are available, too), so it included water out and vent air in. It took a while to find what I wanted, but in the end, I ordered them from US Plastics (they have lots of different options). I plan to do this same setup on our next rig. I will probably use plastic tubes inside the cans next time. The aluminum tubes and blue anodized aircraft AN fittings that I used last time (you can see them in the top photo) seemed to corrode a little over time. Not bad, but plastic might be better next time.
You bring up another good problem to solve. Inside or outside hinge and pneumatics. I would prefer to keep the mechanisms inside to avoid the weather and for aesthetics. This causes a problem though. The hinge and pneumatic use valuable living area and you don't want the tent material to get caught in it. Roofnest has a nice straight up hinge solution (shown below). Does anyone have (4) Roofnest springs they want to sell?Yeah dont do a wedge.. this build is too cool for that.
One thing about hinges is they can compromise the side fabric.
What about the push bar style like you posted a vid to? With nicer execution, could be slick. Lots of other tops use that system.
