Trucks are commercial vehicles. You need them for towing, hauling and other construction related activities. License, permit and tax them as such. If you have a huge boat or RV you need to tow, get and pay for a permit. Have the taxes be based on mileage so the more they're used, the more expensive it is. We invented weigh stations to make trucks compensate for the additional strain they put on roads. Same for these trucks. That'll help prevent them from being daily drivers.
