Trinity is the corner of 3 counties. The community sits in west Pasco just north of both the Pinellas and Hillsborough lines, so a truck that stops at its edge might technically be in any of them. That matters to a dispatcher trying to explain where a driver is, and it does not matter at all to us. RDI Power’s mobile technicians come out from our Brooksville shop, usually by way of the Suncoast Parkway and SR 54, and work on the truck wherever it stopped, with the diagnostic tools to find the fault and the parts and equipment to fix many of them on site.
Finding a stopped truck at Trinity’s 3-county corner
County names are less useful here than road names. These are the ones that matter around Trinity:
- SR 54. The main east to west road on Trinity’s north side. Seven Springs Boulevard (CR 77) and Little Road (CR 1) both meet it in the Seven Springs area next door.
- Trinity Boulevard (CR 996). It runs from the Pinellas line up to SR 54. The corner where it meets SR 54 was once the Tampa Bay Executive Airport, which closed in 2004.
- Little Road (CR 1). A 4 to 6 lane county road built as a bypass of US 19, and Trinity is where it ends.
- Gunn Highway (CR 587). The east end of the busiest SR 54 segment near Trinity.
When you call, give us one of those roads, the nearest cross street or business, your direction and whether the truck is clear of traffic. A map pin from a phone works just as well.
SR 54 between Trinity Boulevard and Gunn Highway
FDOT’s 2025 inventory counted about 57,000 vehicles a day on SR 54 between Trinity Boulevard and Gunn Highway, about 4,617 of them trucks. SR 54 is a Strategic Intermodal System highway in FDOT’s Pasco freight overview, so it carries real freight as well as commuters. A truck that stops in that traffic is a hazard, and the first job is getting it, and you, out of the way. If it will roll, a side street or a lot is far better than the shoulder. If it will not, hazards on, triangles out, and wait well away from the lanes.
Pickups, vans and light trucks: what a Trinity technician fixes on site
Light and medium duty diesels, the pickups, cargo vans, box trucks and service bodies that work around a residential area, fail in recognizable ways, and many of the fixes happen at the curb:
- No-starts and hard starts. Weak batteries, corroded grounds, a tired starter, or glow plug and intake heater faults on cool mornings.
- Limp mode. Sensor and wiring faults, a failed NOx sensor or a DEF system problem that cuts power until it is repaired.
- Charging. Alternators, belts and tensioners.
- Cooling. Hoses, fittings and leaks the technician can reach.
- Fuel. Restricted filters and water in the separator.
The service truck carries dealer-level software, including Ford IDS for Power Stroke trucks and WiTECH for Ram, so the scan goes deeper than a generic code reader. On GM trucks, our service advisor brings 35 years of experience as a technician at a Chevrolet dealership to the conversation. For vans, see our Sprinter van service page. Every visit ends with a digital inspection, photos included, so you can see what was found.
Trinity repairs that go north to the Brooksville shop
Some work cannot be done well at a curb on SR 54: internal engine repairs, transmission replacement, anything that needs a lift. When the diagnosis points there, the technician explains what failed and why, and we schedule the tow and the bay time with you. Because the diagnosis is already done, the truck arrives with parts on order. Labor carries RDI Power’s 3-year, 36,000-mile warranty, or the 2-year, 24,000-mile fleet warranty on RDI Fleet accounts.
