This weekend a built a new bed frame for the bunk room in the fifth wheel.
The bottom bunk just has a couple of folding cushions for use as a mattress, and we need more storage for our 8 week summer trip, so I build a bed frame out of 1" square aluminum tube, aluminum angle bars, and some 1x4 wood slats, so we can fit some rolling storage totes under the bed in the bunk room.
I'll post some photos of it installed in the camper within the next couple of days.

The assembled legs (on the garage floor) before being assembled. I cut and sanded the 1" aluminum square tube to size and used angle braces (with #10-24 flat head bolts and lock nuts) to build the leg frames
