MIKUNI MY30 (made in Japan) , new DIESEL furnace. was intended for boat initially . I purchased this to install in my westfalia camper but decided to go the propane way. This furnace was 1600$ when purchased . comes with install documents /wiring and user guide . output is either 10k btu or 18 depending on setup. It's currently installed in a custom aluminium box . Needs wiring hookup to your boat or camper . 12 volt or 24 and hook up to fuel tank , the pump is attached already . Note it may need another thermostat, this one has no power on switch to manually power or shut the furnace , can be found online OR you put an off on switch . btw I know there are "cheaper" chinese made heaters ... you get what you get !
