A newer version of a battery-powered auxiliary air-conditioning system is now available from Red Dot. The Sleeping Well Arctic 2000 Plus system operates with the truck’s engine off, burning no fuel and producing no emissions. It has an all-12-volt system with twin compressors, upgraded system diagnostics and a wireless remote to control settings. It also has a shore power option and will fit in most sleepers.
