I bought this heater for our homebuilt truck camper after having a similar name brand unit in a sailboat. The camper is a small pop up with canvas sides similar to a Four Wheel Camper. The heater blows 150* at the low setting. We camped in temperatures just below freezing and we turned the heater off because it worked so well. The install was pretty straightforward. The tank is sturdy steel and should last a long time. The heater started up and worked just like it should. The whole system survived a week of being driven and bounced around on rough gravel roads and trails. The unit itself if tiny and easy to find space to mount. I'm still curious as to how long it will last, but overall I'm more than happy with it!
