I should have added that if you look at my frame, you'll see that the missing crossmember is at the foot of the bed where there won't be much weight. The galley and the head and center sections of the bed are all supported by cross-members. I suppose I could have supported that by adding a cross-member on my
wooden base frame to correspond to the place where the missing frame member would have been, but I didn't.
It has now travelled about two thousand miles and it hasn't been a problem.
