Installing a wire shelf into the end bunk of a pop up camper.
I know the shelf is not perfectly level, but we didn't realize it until we had already installed it. We used a level to decide where to mark to install the back part of the shelf, but the camper had not been levelled when we did that. The best way would have been to measure up the upright post from the floor of the bunk to where we wanted the back of the shelf to rest, and then drill the holes at the same height on both sides. (?) Oh, well... live and learn.
