Few people have 4 link special air ride suspensions in their 3/4 ton trucks.
Don't forget that if you have duals, you have a backup tire if one shreds. And trucks towing heavy loads do have blowouts. But most trucks towing boats are not getting up to the maximum tow weights where a 1 ton is required.
