In the world of smoking, the cheaper smokers (New Braunfels, Bar B Chef, Brinkmann) have legs caps. A rule of thumb is not to install the leg caps for the following reason. If water were to somehow get inside the leg then the cap would trap it and rust out the leg (i.e no place for the water to flow). I actually saw this happen on a couple New Braunfels I looked at last year. What do you guys think??
