I am going to buy a hard tonneau cover, so the toolbox won't fit my truck anymore. It is in very good condition. $250 takes it, local in AZ as it's too large to ship cost effectively. I don't have any pictures of it on my truck to post right now, I'll post them tomorrow if need be.
I just ordered my cover, I'm not sure if the sliding bed divider will still fit or not. If it won't fit it will be for sale shortly.
It weighs about 35 pounds as these are made of aluminum. The outside dimensions are 63w 20d 18h including the side hardware that could be unbolted for a width of 59". I have a feeling that unless it was crated the carrier would have a 99% chance of destroying it.
Cost about $100 to ship, thats 350ish. Your price is good but unfortunatly I live to far away. If you don't get any bites and want to go lower let me know.
If the toolbox is empty it weighs about 25 lbs and can be removed in about two minutes by one person. If it is loaded you will likely need two people to lift it off the utilitrac rails. It uses a single key and mechanism to open it from the driver's side.
It is removed as follows: Open the toolbox, release the mechanism that secures it to the front of the bed, release the securing knobs (one on each side), slide the toolbox to the end of the bed, carefully remove it from the utilitrac rails. I removed it from mine the other day. In my case I had to remove the bed divider first, then remove the toolbox.
