Without a normal footboard, at the end of an RV bed, there is a tendency for the blankets to slowly work their way off the end of the bed, which leaves you constantly pulling them up during the night. I tried various methods of holding the sheets and blankets on the bed, and finally made two short footboards, which just slide under the mattress after the bed is made. Your bedspread goes over the top to hide them.
The upright is 1/2" plywood, this apparatus needs to be light. The bottom is 1/4" Masonite. I glued and used wood screws for strength. Make two, one for each side of the bed at the bottom. Keep the upright a few inches below your mattress height, so you can still sit on the end of the bed. Our mattress with topper is 14" thick, and the 9" height of the footboard works fine. Two footboards are easier to manage than one, and there is a space between for your electric blanket cord.
Bedspread goes over the top of the footboards.
It took me a couple of shots to get this right. The first ones I made did not include the base piece, and they easily broke. Gluing and screwing the base to the upright is essential for strength. The budget for this project was about $10.
