WATER & TANK SYSTEMS
Engineered for extended off-grid travel and long-term reliability.
Revolution Motorhomes designs its water and tank systems with the same engineering-led philosophy applied to the entire vehicle. Capacity, weight distribution, material safety and ease of use are all considered from the earliest design stage to support extended off-grid travel in Australian conditions.
Custom-Made Water Tanks
Lightweight. Strong. Purpose-built.
Revolution’s Mercedes Sprinter LWB 7.48 m motorhomes feature a standard freshwater capacity of 210 litres, expandable to 280 litres, and optionable up to 325 litres (light truck licence required).
Greywater capacity starts at 90 litres, depending on toilet selection and freshwater capacity, with upgrade options to 135 litres or just under 200 litres.

Off-Grid & Gasless Options
Setting a new benchmark.
Revolution offers advanced off-grid and gasless configurations, developed to reduce reliance on gas while increasing autonomy.
Key features include:
• Increased battery capacity
• Expanded solar charging systems
• More powerful, less intrusive remote-start generator
• Increased water capacity compared to competitors
• Optional 240-volt external BBQ
• Optional diesel hot water system replacing gas
Nearly 50% of customers now choose induction cooktops, paired with diesel under-floor air heating as standard — creating a true off-grid, low-gas motorhome solution.
Advanced Composite Tank Construction
Safer materials. Superior durability.
Revolution’s composite water tanks are manufactured using fibreglass, carbon fibre and HDPE non-toxic nylon.
These tanks are significantly lighter and stronger than traditional RV tanks and prevent toxic chemical leaching into freshwater supplies.
Gas Capacity & System Design
Extended autonomy without compromise.
While many luxury motorhomes are limited to two 4.5 kg gas bottles, Revolution motorhomes can carry two 9 kg gas bottles.
The bottles are mounted higher for easier handling and reduced physical strain, improving safety and everyday usability.

Integrated Toilet System
Cleaner. Quieter. Smarter.
Revolution has engineered a new toilet system to eliminate common RV issues such as:
• Odours• Noisy macerator pumps• Vacuum pump disturbances• Heavy, manually emptied waste containers• The system features• Composite fibreglass holding tank• Advanced odour extraction• App-controlled emptying and cleaning process
Emptying the tank is completed by connecting the waste hose and activating the system via the phone app. Once emptied, the system automatically flushes and cleans the holding tank, sender and hose.

Why It Matters
Designed for real-world touring.
Every element of Revolution’s water and tank systems is designed to:
• Support longer off-grid stays
• Reduce maintenance and weigh
• Improve safety and usability
• Perform reliably in Australian conditions
Frequently asked questions
1. How much water capacity does a Revolution motorhome have?
Revolution motorhomes offer freshwater capacities starting from 210 litres, with upgrade options up to 325 litres depending on model and licence category. Grey water capacity starts at 90 litres, with upgrades available up to nearly 200 litres.
2. Why are composite water tanks better than traditional RV tanks?
Revolution uses composite tanks manufactured from fibreglass, carbon fibre and HDPE nylon. These materials are lighter, stronger and food-safe, preventing chemical leaching and improving long-term durability compared to traditional plastic RV tanks.
3. How do Revolution motorhomes support long-term off-grid water use?
Water system design is integrated with weight distribution, off-grid power systems and automated waste management. This allows extended off-grid travel while maintaining safety, reliability and ease of use in Australian conditions.
4. Why does water system design matter for Australian touring conditions?
Australian touring involves heat, distance and limited access to services. Revolution’s water systems are engineered to perform reliably in high temperatures, reduce maintenance, and support longer off-grid stays without compromising safety.
