Where is a good place in the coach (Axis 25.2) to check for level. I have read that some level the frige. I can place the level on the frige freezer door and it is different on the frige door, I can place it on the cabinet around the frige and it is different as well. It doesn't matter where I place it in the coach, the floor, the counter, the table or even the exterior door from the out side it is different. I can place it on the floor in 3 different spots and all 3 will be different.
