In the future, HVAC service trucks may have a whole new look to them - or they may not. To the naked eye, the trucks may look similar on the outside, but there might be a radically different appearance on the inside. The fit and functionality of trucks may be a whole lot different from their ancestors, the standard van of today, which has been commonplace for decades.
Future service trucks will likely embody a lot of new technology, making it easier for the driver/technician to communicate with his company, customers, supply house, etc. The tech may even have the ability to contact the local municipality to pull a permit, download it, and print it out in the van before arriving at the jobsite.
