I am looking at buying a single Axel 31k GVW truck. When I contacted my insurance company they said it would be $2k for 1 mil comprehensive coverage of the truck and 18 foot 5 ton trailer I currently have. My question is how many people just have collision and liability coverage and what do they pay for single axles? The second question is how do you bill for hauling with a single? I plan to only haul when people need 8 tons or less of material but I'm not sure how to bill. How much do most people add on top of gas and material cost?
