Running a service fleet myself, the honest answer is that clean lettering with a big readable phone number outperforms an expensive full wrap almost every time. People read your vehicle from two lanes over at speed, so contrast and size beat artwork. We had our vans and trailer done at SmartSwans https://smartswans.com/vehicle-wraps-branding/ with business vehicle lettering and partial wraps, and they cover fleet branding and trailer graphics too, so all three matched. They also have guides on box truck and contractor trailer graphics, including where a QR code actually works. Since your trailer sits at sites all day, put the service list and number on its sides rather than the rear, that is the panel people see.
