Getting Personal Property Insurance for your rig.

I have spoken to my insurance agent who told me my particular policy does not cover systems of this nature, but some policies do not have these limitations on categories of personal property.  For now, my system is more or less not covered, the caps are so low.  However, my agent told me that when it comes to renewal time, we can find an insurance policy that does not have any particular category limit, and personal property will cover it, with proper documentation.  

Call and and talk to different insurance brokers rather than insurance companies themselves and you should find what you are looking for.
