Thanks for the reply. This is great. A little Klingon at the moment, which I do not speak, but it seems that 4 cross support should hold us. I will check the calculation, but since I plan to install them in an L track, adding one should not be an issue.Hi, for a 90" bed, 3 beams would be spaced almost 45" apart each.
0" at one end
~90" other end
There are plywood deflection tables at
Hope still on to have a bed that does not bend the chassis or collapses on the floor from 3 feet high.
