Some time ago i was tired of the standard container ship (driveable) and downloaded a larger one very good looking.  So far so good.  But this one had a ton of containers, and when downloading I populated my list of assets with Gb's of assets, trucks and all.  So, I deleted it all and returned to a basic one (it was a little large for me).  Would be nice:  If the ship would be "empty" and ready to accept whatever you decide.  Naturally some of you would say, "easy, delete at config file and you'll have it", well, not so easy but doable, problem is that I don't have the time to monkey deleting lines and lines of assets, to find at the end that there are missing assets or others, and be frustrated.  That is my answer.
