I have insured everything. The $1,000,000 liabilty is the large part, but I put $10,000 insurance on my enclosed trailer and all the tools inside, and the insurance for the pickup is included. I think the enclosed trailer and tools comes to about $60/year. That is too cheap to not cover it. You might check to make sure that you are covered, in case of a vehicle accident, tornado, flood, etc. I would guess that replacement value on a machine would be pennies per month.
