MikeV, I think you meant a higher box, but I have another suggestion.

OP, when you go to the lady Lake post office see if they have an insert that can be used with your mail box. If so this might work for you as you would have a single item to grab. Also, if the post office does not have this, ask if they would object if you obtained one and would they use it? The other option would probably be to have your mail forwarded to one of the pack and ship, but I do not think this can be done on a permanent basis.
Hope these ideas help.
