Complaint up front- it was missing instructions, and the controller isn't very intuitive to use. But a little searching got me the info I needed for setup, and after playing with the controller a bit I figured it out well enough. I'm still not in love with the controller- it works wells enough though.Other than those gripes- well packed and everything as described. Quality of everything seems good.I'm going to be installing this in an "adventure" van that I haven't bought yet. I wanted to test it out though so I set it up on a small frame. I don't have any way to exactly measure the heat it puts out, but comparing it to the typical 1200 or so watts a typical electric heater puts out, 5000kw seems about right. It's a lot of heat, way more than needed to keep a typical room warm- I was heating my living room, kitchen at a bit more- about 700sf of space with it.I'm sure it'll be way more than enough for a van I- I expect it would be fine for the typical RV, unless it was enormous, or uninsulated, or you were in crazy Siberian cold.Also I'll note it's louder than I expected it to be. BUT I had it totally out in the open- typically you mount these inside cabinetry or under something. So I expect when it's finally installed the noise won't be unusually loud.
