A fleet that works Casselberry spends its day on US 17/92 and SR 436, two roads that carry about 63,500 and 49,000 vehicles a day near the city. Their junction averaged about three crashes a day before the 2015 flyover was built. For a fleet manager, that history makes a simple point: in heavy traffic, the maintenance that matters most is the maintenance that keeps a truck able to stop, steer and be seen. RDI Fleet, RDI Power’s fleet program, puts those checks at the center of every visit, then covers everything else a diesel needs to stay in service.
Casselberry traffic and the case for brake and tire records
Corridor driving puts more work through brakes than highway miles do, and Florida heat adds to tire and cooling stress. On an RDI Fleet plan, brake linings are measured and recorded at every visit, and on air-brake trucks the technician checks adjustment and looks for air leaks. Tires are checked for tread depth, pressure, wear pattern and sidewall damage. Because each finding goes into a digital inspection with photos, you can watch wear trend over months instead of discovering it on the day something fails.
That record has another use. If one of your trucks is ever involved in a collision on US 17/92, a documented maintenance history showing measured brakes and checked tires is a far better position than having nothing on paper.
What a Casselberry PM visit checks first
Safety items lead the list, followed by the items that keep the truck running:
- Brakes, steering linkage and suspension components
- Tires, wheels and wheel ends
- Lights, reflectors, wipers, horn and mirrors
- Engine oil and filter, plus fuel filtration
- Coolant, belts, hoses and the radiator
- Batteries and the charging and starting system
- Aftertreatment (DPF, DEF and EGR) and any fault codes the truck has logged
Visits happen at your yard on the days you choose, several units can be handled in one trip, and anything that needs a lift is scheduled into our Brooksville shop.
Driver pre-trip checks and Casselberry annual inspections
A maintenance plan does not replace the driver’s pre-trip inspection; drivers remain responsible for checking their vehicle before they roll. What the plan adds is the deeper, scheduled look that a pre-trip cannot provide. Federal rules set the floor: a commercial vehicle rated at 10,001 pounds or more and used across state lines gets an annual inspection, and you hold onto that report for 14 months. RDI Fleet books each unit’s annual alongside its PM, and anything that does not pass is photographed, written up and fixed once you approve it. For the inspection checklist itself, see DOT inspections.
Bringing a Casselberry fleet onto a plan
Getting started takes a phone call and a yard visit. On the call, we go through how many units you run, what classes they are, where they park and which ones are giving you trouble now. Then a technician comes to your Casselberry yard, looks over each unit, records its engine, its mileage or hours and its condition, and flags anything that affects safety so it can be dealt with first. From that inventory we set intervals for each class, date the annual inspections and hand you a schedule built around the days your trucks can be spared. The first round of PM usually tells us a lot, and the intervals are adjusted from there.
Casselberry route trucks and haulers on a plan
Casselberry’s commercial solid waste runs under an exclusive agreement with one hauler, GFL Solid Waste Southeast, while residential collection runs under a separate city program. Refuse routes are the extreme version of corridor driving: constant stops, heavy loads, long idle. Any unit with a day like that, whether a refuse truck, a delivery box truck or a service van, is best tracked on engine hours, with brakes and cooling checked at every visit and the PM timed so the truck is never far past due. Mixed fleets are normal, and pickups, box trucks, tractors, trailers and buses can all share one plan with intervals set for each class.
Diagnostics for Casselberry units between visits
When a truck sets a code between scheduled visits, fleet accounts move to the front of the line, and the diagnosis is done properly the first time. RDI has Ford IDS for Power Stroke trucks and WiTECH for Ram and other Stellantis vehicles, heavy-duty software for tractors and vocational trucks, and a team that includes ASE certified technicians and a Ford specialist with more than 30 years at a Ford dealership. A real diagnosis means fewer parts replaced on a guess and fewer trucks back in the shop a month later.
Fleet warranty and roadside for Casselberry units
The RDI Fleet warranty covers fleet repairs for 2 years or 24,000 miles. Fleet accounts also have 24/7 roadside assistance, so a unit that stops near the SR 436 flyover at night is covered.
See the RDI Fleet maintenance program, fleet maintenance in Winter Springs for the neighboring city, or mobile diesel repair in Casselberry for breakdowns. Call (352) 433-3800 and tell us how your Casselberry units run.
