Trinity is a planned residential community in the far southwest corner of Pasco County, right where Pasco, Hillsborough and Pinellas meet. A van or pickup based here can start the day on Trinity Boulevard, cross into Pinellas for its first stop and finish in Hillsborough. That makes maintenance easy to put off, because the vehicles are always somewhere else. RDI Fleet, RDI Power’s fleet program, fixes that with a plan: preventive maintenance on a calendar, done at your yard by technicians who drive out from our Brooksville shop, and a record of every unit.
Trinity fleets that cross 3 county lines
If your operation services, delivers to or works on homes and businesses around this corner of Tampa Bay, your vehicles live on the same handful of roads: SR 54 to the north, Trinity Boulevard (CR 996) down to the Pinellas line, and Little Road (CR 1), the county’s bypass of US 19, which ends at Trinity. Public transit runs here too; GoPasco Route 23 links Trinity with Hudson.
None of the county lines matter to us. The plan follows your vehicles. If they park at more than one location, we build the visit schedule around each one.
Stop-and-go miles on SR 54 and Little Road near Trinity
FDOT counted about 57,000 vehicles a day on SR 54 between Trinity Boulevard and Gunn Highway in 2025, roughly 4,617 of them trucks. A van that spends its day on that road and on Little Road covers fewer miles than its hours on the clock suggest. The odometer undercounts the work, and a schedule built only on miles will be late on oil, filters and brakes.
So we look at other numbers too. The engine control module records idle hours, total engine hours and regeneration events, and those figures come off every unit at each visit. A van whose idle time is climbing gets its oil interval pulled in. One whose DPF keeps starting regenerations it never finishes gets a closer look at its sensors and its route before the filter plugs. Brake linings are measured, not eyeballed, and batteries get a load test rather than a voltage check. Over a few months, that data tells us the right interval for each vehicle, and we adjust the plan as it comes in.
A Trinity plan for vans and light trucks
A plan for a service or delivery fleet often covers a mix of light and medium duty units: diesel pickups from Ford, Ram, GM and Nissan, Sprinter and other cargo vans, and a few box trucks. Each class gets its own checklist and its own interval. Pickups that tow get closer attention to brakes, transmission fluid and hitch hardware. Vans get their DEF systems, glow plugs and electrical loads checked. Box trucks with liftgates get the hydraulic and electrical side looked at alongside the engine. Trailers, if you run them, are inspected with the truck that pulls them.
Units that need a yearly federal inspection get it on the same visit as their PM, so the paperwork stays current without a separate trip. Federal rules require that annual inspection for commercial vehicles in interstate commerce with a GVWR of 10,001 pounds or more, and the report stays in your records for 14 months. What the inspector looks at, item by item, is listed on the DOT inspections page.
Visits, records and roadside for Trinity units
Technicians come out on dates set around your operation, often when a group of vehicles is parked for the afternoon or on your slowest weekday. One visit covers several units. Anything that needs a bay, major engine or transmission work, is booked into the Brooksville shop, where fleet accounts move to the front of the line.
Each visit leaves a digital vehicle inspection, with photos of every finding, the technician’s notes and a list of what should come next. Over a year those reports show which vehicles cost the most and which ones are approaching replacement. Fleet repairs are warrantied for 2 years or 24,000 miles, and when a Trinity unit stops on SR 54 after hours, fleet customers have roadside help 24/7.
For a single breakdown, our Trinity mobile diesel repair page explains on-site service. Operators on the Hillsborough side can read about fleet maintenance in Keystone. How the program works from start to finish is laid out under RDI Fleet maintenance. Call (352) 433-3800 and walk us through your vehicles.
