This is the 3rd heater I have bought. I should have paid the little bit extra to get this brand in the past. Knowing that the cowling has to come off from time to time. The latches is the big plus as the other two will have stripped out holes in no time. One already has a larger screw it in. The fuel line and how it's routed. Safety minded. Pay the little extra bit of $ and save your self problems.
