Several members have requested a water tank for the spare tire bay on the R1T. This is the mid sized design at 7 inches tall and 20 gallons. I have also done a "Max Pack" full height at 30 gallons, but more on that later.
The tank is roto-molded with 4mm thick walls. The removable access hatch is PVC. The hard mounted 12VDC pump is submersible. It has holes in the bottom for simple PVC pipe legs that allow you to use the empty tank as a seriously funky / cool camp table--thanks for the idea Jeff =)
The arrowheads--which double as cup holders in table mode--and subtle tribal look are a nod to the Indian in Rivian's name. For those that are not aware, Rivian is derived from River and Indian       Attachments:

I am interested in you tank.
I am looking for such a tank that I can use the cable/chain that is used to winch up the spare into the space to get the tank in position. I would then have a metal plate that it would sit on that would in turn be connected to the metal crossbar with some all thread rods to support the weight.
You photos do not show a hole through the center of the tank which seems to me would be a mistake for this application.
What thinkest thou?
Curiously yours,
Jim

I would think that you would want to make this as generic as possible so it can fit under and vehicle that carries a spare wheel/tire using a cable/chain winch to get the spare up and down when it is needed.
Every pickup on the road carries a spare this way.
Curiously yours,
Jim

![]( "Right click to shift") That does seem obvious at first blush of course, but the Rivian tire bay is accessible from the top via a flip up cover--which is where the water tank would be accessed from as well. That being said, if a single design can work well for both, all the better. The non Rivian version might be just the raw tank without a pump so that other vehicle owners can customize as needed for their particular truck. |

While I am planing on installing a pump, if it is in the tank and access in order to repair/replace is not an issue, I would go for the pump as it simplifies my life in not having to allocate already limited space in my camper shell for the pump.
I have a roof top tent on the shell with a solar panel on the cab along with a storage box that share the space on the roof rack on the cab of the truck.
Everything else has to go in the rear of the cab or the camper shell.
This is why I am looking for a relatively easy way to mount a water tank. If I do not have to remove the existing winch for the spare tire and can use it to lift the tank during installation, that is a plus. I would still need to install mounting brackets to help support the weight of the water/tank. That is no problem; I have several ideas in mind but really cannot do anything to engineer it until I have the tank on hand.
The only place I have found such a tank is in Australia and no one will ship to the USA. The only tank in the use is made for gasoline with the maker marketing it as being for water because it does not meet federal specs for a fuel tank. the only inlet/outlet is threaded for a fuel container cap and pour spout. It is not intended to be used while attached to the vehicle.
I have see photos of some hack jobs to get a decent 1.5 in. fill connecton, a vent and an outlet. UGH! a recipe for disaster in my opinion. I spend too much time on unimproved road to trust my water supply to something that could come apart just from the vibration.
So, I think you are on to something with your design. The only issue in my mind is the hole in the center of the tank. I have spoken with several manufacturers but the ramp up cost is not something I can take on. Your idea is the best I have seen in the USA.

![]( "Right click to shift") Have you seen these 6 gallon stackable tanks? www.trailedonline.com/product-page/4runner-and-tacoma-6-gallon-spare-tank-2-packIt would be fairly easy to make or have a manifold machined to connect as many of those as you needed together. |

That tank is the very one I mentioned that has a screw on cap that is the same size/thread as a gasoline container and will only take a spout that would fit a gasoline container. Not plumbed for a vent or another opening. This means it must be removed from the spare tire position to fill and empty.
There are some hack jobs linked to the site showing what people have done to try to make work as water tanks that can remain on the vehicle. Not anything I would stake my life on in the boonies where losing your water supply could mean death.

Does the Rivian R1T spare stow from the bottom? A hole in the center wouldn't hard to do bot I don't think it is needed for the Rivian. The spare is held in place with a threaded center post. A hole could be utilized in the same way. Anyone with the spare (and a different location for the tire...) would still have the threaded rod and ability to set it down and lock it in place with the existing hardware. The other option is that you could include something to do that with the tank if/when it comes to fruition... |

There doesn't seem to be much interest in this project which is a shame as it would be pretty simple to do. Many of the people I've talked to are waiting until the Frunk tank gets delivered before they really believe that anything is coming... /shrug Hopefully once that tank is delivered and you start work on some others, this might be one that can run in parallel, since it'll hopefully be pretty simple... One other thing to note, is the people who are going to need this much water are quite likely the people who are going to want a spare tire... So, right now, there's only one other option which is the Dirtcom hitch swing that fits the Rivian. As more tire relocation options become available, there may be more interest in utilizing the space it frees up by moving it... |

How about a water tank for the sub-trunk of the R1S? You could by skip installing a pump by installing a Schrader valve and use the air compressor to pressurize the tank. Similar to the Klymit WaterPort 4.0 tank.

Similar to the Klymit WaterPort 4.0 tank. A tank for the sub trunk would be easy to do--I already have a 3D scans--but I don't think there are enough people interested in it. As for pressurizing the tank with the air compressor. I get this suggestion fairly often as it is one of those things that sounds cool but in reality it just isn't practical for several reasons. A tank strong enough to be pressurized would need to be metal so quite heavy and expensive. A significant portion of your available volume would be needed for air rather than water. Most importantly, air compressors also spit out a bit of oil/lubricant--not something anyone would want in their water. |

That’s a good point about the oil/lubricant from the air compressor. I never thought of that. You’re right, a pump is the way to go.
As for an R1S sub trunk water tank, I obviously would be interested if you ever made one. And since there is way more buyers for the R1S in general, would it be worth putting out feelers for it?
