What advice do you have for rental car insurance coverage?

You can purchase hired automobile physical damage on your automobile policy. We have two areas of caution. First, your rental agreement may require you to reimburse the rental company for their loss of rental income when their vehicle is wrecked. Most policies do not cover that exposure (but many credit cards do). Second, this coverage only applies to the named insured of this policy. When you rent your vehicle, remember to draw up the contract with your company name. If the rental agency does not allow that, then make sure that you sign your name followed by "on behalf of" your company name.
