Didn't find any other threads on MV insurance so I thought I would post it here.
I know more than a few people have a hard time finding insurance for these things. We either get a blank stare from the insurance companies or they simply state no. And the rare time they say yes, they want to charge you a metric ton even though it only leaves the yard a dozen times a year.
Found a great company here in Ontario that will insure pretty much any MV without a problem. When we called up and asked if they insure a MV we got a "sure, not a problem" as an answer.
The company is called Zehr Insurance Brokers Ltd in New Hamburg, Ontario.

We deal with Dave Stewart in their Vintage Car division. He is very helpful and got our whole fleet insured pretty quickly for a great price.
They got us under a fleet insurance due to all the vehicles, but they will also insure just one vehicle if that is what you got (though you should buy more because it is fun).
Hope that helps anyone looking for insurance.
