Camper commercial rental insurance

[Dan Stewart]

A little off topic but I have decided to turn my camper into an asset. I was going to deliver my camper to the local sites for people to use but I am getting request for people to take it off my hands and drive it around the state of Michigan. I have turned down thousands of dollars because I don't' want to take the risk of someone destroying my camper driving. My insurance won't cover someone else towning the camper. 

I have been looking into some sort of insurance for the camper but can't seem to get anywhere with it. I figure it's a long shot considering this is a real estate forum but has anyone ever done this? What insurance companies did you use?

Thanks in advance for any directions
