Thanks to Randy and Scott for your input!
The company I am considering does not provide insurance. The best rate on comp and collision plus the non-trucking liability insurance that I have found is $326.00/month.
I have checked with those companies who offer group rates when you are driving for them and one rate was $120.00/month, but they pay 10 cents less per mile and their monthly fees (Qualcomm, sign up, etc) are going to average another $100.00+ per month.
Initially it appears that I would be money ahead by going with the company I mentioned and bearing the cost of the insurance myself.
