I have only had it installed a couple weeks so i cant speak on the longevity of the unit, but i will say it cranks out heat. I have a 40' destination trailer. I mounted this unit in a tongue box and piped it in the wall. With both my furnace and this running it heats up from 55⁰ to 65⁰ in less than a half hr. The fuel consumption is relatively low unless i keep it running all night in which case it uses about a gallon of diesel. The remote is handy. The bluetooth app is absolute garbage tho. I got it to work once and not again. I also am not sure where the thermostat is located but the auto feature doesnt seem to work either.
