Hi Carl,
What a pickle you are in! Getting the correct General liability for a Storage business is a nightmare!
I do not have an answer, but I recommend you contact an escrow officer at a title company to see what insight or pathways they might offer, such as deeding that parcel of land to your child, relative, etc. Then, work with them to get the coverage you need. In addition, there should be an attorney affiliated with the company that hopefully is savvy in real estate law.
