Sleep number
Bought a Sleep Number radius king that came with corner locks for the head of the bed, but nothing to join the foam walls at the foot. Currently have them joined with a couple of L-shaped corner locks...

Same here, square at head and rounded at the foot. Biggest problem many times is the short RV plate form the matteress is on. Our sleep number is now in it's third 5er and on each I have pulled in the slide and replaced the OEM plywood and installed one wider and longer (as long as I could go without hitting anything).
