I need to also figure out a long term plan for these beds, they will not last forever. I am thinking about wrapping them with sheet metal and steel posts. Then when the beds fall apart they will just stay inside of the metal enclosure.
Yeah, it is a better idea, in my dormitory area they did the same thing which is very convenient and maintenance-free for a long time. They installed the basement with concrete and iron bars and made some stronger columb at a distance connected with the stronger basement in the ground and then installed the thick iron sheet, and finally connected each of the sheets by soldering them to make them watertight.
Oh cool yeah I think I will be going with metal beds soon enough. That should hold up much better to the elements and be stronger to hold lots of dirt.
Indeed!
