We are using this little heater for a cargo trailer conversion and this little guy heats it up nicely. It only took me about 20 minutes to install into the trailer, cutting the holes to go underneath for the intake and exhaust. The down side is the fuel pump knocking sound. This seems to be the norm with these type of heaters, and with the fuel pump in the metal case, it uses the case to transfer the sound more. I plan to build a surround around it and remove the fuel pump and relocate it within a separate case to block the noise out. All-in-all this is a powerful little heater, and for the price I would highly recommend it. Many of these little heaters you have to put together, this one was all complete, just the intake and exhaust that you have to install. Skill level 1.Ok lets talk about the instructions and manual for this unit. Not the best. I got most of my info from watching Youtube videos from others with similar heater setups. The control panel is pretty simple but has a bit of a learning curve to it. I have yet to still get the remote to pair with it, but should be pretty simple. Time will tell, but again for the price this is a good deal and would recommend it.
