A truck based in Union Park can spend the morning at expressway speed and the afternoon crawling. SR-408 and SR-417 meet at Exit 18 on the community’s edge, FDOT counts about 6,901 trucks a day on SR-408 nearby, and SR 50, widened to 6 lanes from SR 436 to Dean Road, carries about 2,525 trucks a day of its own. That split duty cycle is the starting point for any RDI Fleet plan here. RDI Fleet is RDI Power’s fleet program: a written plan, scheduled preventive maintenance, priority service, digital inspection reports, a fleet warranty and 24/7 roadside for accounts.
Mixed duty cycles on Union Park’s toll roads and SR 50
Highway miles and city miles wear a diesel differently. At steady expressway speed, the engine runs hot enough to keep its particulate filter clean and the oil stays in good shape for longer. In stop-and-go traffic, with frequent idling, brakes wear faster, soot builds up and the engine logs hours that the odometer never shows. A Union Park unit that does both needs a schedule that accounts for both.
So we track miles and engine hours side by side for each unit and service it by whichever comes first. Brake linings get measured on every visit, not just when they squeal. Aftertreatment is checked each time, and cooling systems get a close look, because Florida heat and idle time are a hard combination.
What a Union Park plan writes down
The plan is short and specific:
- Every unit. Year, make, engine, miles, hours and what it does on a normal day.
- Intervals. Oil, filters, chassis lube and inspections by miles, hours or calendar, class by class.
- Inspection dates. Each unit’s annual inspection on the same calendar as its PM.
- The budget. Which repairs are urgent, which can wait a quarter and which only need watching.
Light duty pickups and vans, medium duty trucks, heavy tractors, trailers and buses can all sit on one account. Our oil and lube page explains why intervals matter as much as the oil itself. A unit that changes jobs, say from highway runs to local work, gets its schedule revisited rather than left on old numbers.
Annual inspections and priority for Union Park units
Union Park units used interstate and rated 10,001 pounds GVWR or more need a federal annual inspection, and the report stays on file 14 months. Drivers remain responsible for the pre-trip each day. In a Union Park plan, each annual is booked into the same visit as the unit’s PM, and anything that fails is photographed and quoted before it is repaired.
A broken fleet unit takes precedence in our schedule. The person who takes the call already has the truck’s history from past inspections, so the diagnosis starts from what is known about that unit rather than from scratch.
Yard visits for Union Park units
For a Union Park account, the yard is the workshop. A technician drives out from Brooksville on a scheduled day, planned around your operation and grouped so one visit covers several units. PM, inspections and smaller repairs are done at the yard. If a unit needs a lift, say for internal engine repairs or transmission work, the trip to Brooksville is booked ahead with you instead of forced by a breakdown.
A yard visit needs little from you: a firm, level spot to work, the keys, the unit list and any driver complaints. If your units park at a shared lot or a job site rather than a dedicated yard, tell us. As long as the ground is solid and there is room to work safely, the visit can happen there.
Fleet warranty and roadside for Union Park
Photo-backed inspection reports from each visit become each unit’s service history, and after a year they show which units cost the most to keep running, so replacement decisions rest on the record. Fleet repairs on the account are backed for 2 years or 24,000 miles. When a unit stops on SR-408 at night or near the Dean Road toll plaza on a weekend, 24/7 roadside assistance applies.
