One of our customers recently shared their clever and practical water system built for the Tesla Cybertruck, combining hot water delivery, thoughtful mounting, and smart power use - all tied into the truck’s 48V accessory line. It’s a perfect example of how the Urander platform opens the door to real-world upgrades that enhance everyday overlanding life.
Here’s the setup:
"I added WaterPort’s 'under' rack mounts with an 8-gallon WaterPort Weekender and a 4-gallon Yakima RoadShower. The RoadShower is aluminum and allows for a little easy engineering where I added a heating element and a thermostat that runs off the Cybertruck roof 48V accessory feed."
The heating system uses a threaded 36–48V DC heating element, drawing only about 200 watts per hour, and brings 4 gallons of water up to 118°F (47°C) in roughly 70 to 90 minutes - plenty for a warm rinse, quick dish clean-up, or even a cozy night in your rooftop tent.
They also noted:
"It is pretty awesome that the Cybertruck with the Urander allows this functionality."

Step-by-Step Instructions
-
Connect to your Cybertruck’s 48V roof accessory line
Use XT-style connectors for an easy plug-and-play setup. -
Install the heating element
Thread it into the brass M14 adaptor. Hand-tighten firmly—there’s a gasket to create a seal. -
Mount the assembly into the RoadShower
Tighten the adaptor with a 7/8" wrench about 1/4 to 1/2 turn past snug. -
Wire the heating element
Tie the pigtails into your 48V line. Add a detachable connector close to the canister so you can disconnect it easily. -
Power it on
Use your Cybertruck touchscreen to activate the 48V accessory line. Monitor the temperature using the built-in sticker thermometer or install an external sensor. -
Optional thermostat upgrade
The user added a temperature sensor around the RoadShower and wired it to auto-shutoff at 118°F (47°C) for safety.
Pro Tips
-
The RoadShower includes both a shower head and spray nozzle with quick-connects. We recommend getting both.
-
You can pressurize the tank with a tire pump thanks to its built-in Schrader valve.
-
There’s also a pressure relief valve set at 55 PSI to keep things safe.
-
No thermostat by default - monitor temp and mix in cold water if needed.
This setup adds serious functionality to your Cybertruck without adding much weight or complexity. Just another way Cybertruck owners are pushing boundaries - and getting creative while doing it.

Extra Details from the Builder
"I also added Cybergirl’s Lipert winch spare-tire system for hanging a spare tire off the bottom rear of the Urander. But I’ve got to move that a little, as right now the spare is a little too close to my WaterPort Weekender and Yakima RoadShower."
This setup shows what’s possible when creativity meets capability. With the Cybertruck’s roof accessory power and Urander’s rack platform, you're free to build a system that fits your exact needs - whether that’s a mobile shower, a dishwashing station, a low-power heating source for your tent, or even hanging a spare tire off the bottom rear of the rack to save space and optimize gear layout.
