Can't help ya on that most recent question, but thought of one more thing that might be good to know....

If you plan to sell cd's, tapes of any kind, electronics, etc...when storing them, keep in mind that they WILL melt at some point of heat. If your trailer isn't stored somewhere cool, then I wouldn't put these items in it! Also, when displaying them at the sale...direct sunlight can warp, melt, etc these type of things so plan to have some way to shade them a bit if its going to be warm!

HTH!
