i know it's kinda vague, but roughly how many full size motorcycles (no saddlebags) (all center standed or wheel chocked) will fit in a 40' shipping container for long term storage? i really don't need access to any of them - i just want them out of the way for a few years. i would assume around 20? i would arrange them i assume forward/reverse/forward etc. along the one long wall... anyone using a shipping container for long term storage? i would guess temp sensor ventilation is one of the main things to add?
