commercial truck insurance in Cincinnati

[DL Martin]

 Hi;

I have a 2000 Ford E350 17' box truck that I use as a mobile supply house/tool storage center. The truck is driven less than 5,000 miles per year and is located in Cincinnati, Ohio. 

The insurance policy is up for renewal and the annual premium is $457. This includes comprehensive, theft , uninsured motorist, and I believe has a $500 deductible. I am the only person who drives the truck. 

Does this seem like a decent rate or should I be shopping around? 

The current policy is with Progressive. 

Thanks

DL
