Question about properly sliding bunks in and out? When sliding bunks in, does the end of the bed(end with strap) go over the bed slide ramps(white Teflon squares) and set behind the bed slide ramp which allows the entire bunk end to set on top of end wall instead of setting on top of the Teflon bed slide ramp. I just want to make sure I'm doing this right and that I'm not putting undue stress on my bed rails. Thanks!!
