The Dometic RM4805 and Dometic RM4808 are among the largest 3-way absorption refrigerators installed in caravans and motorhomes. Designed for extended touring and long-term travel, these premium two-door fridge/freezers offer approximately 224 litres of total storage capacity and can operate on LPG gas, 12V DC or 240V AC power.
The RM4808 was introduced as the successor to the RM4805, retaining the same cabinet size while incorporating updated electronics and improved control systems.
Although both models are now discontinued, they remain highly sought-after refrigerators and many are still operating throughout Australia. As a result, replacement parts continue to be in strong demand.
