A fleet of service vans and light-duty pickups working Lake Mary’s office corridor has its own maintenance profile. Since the late 1980s, the city’s office, retail and industrial growth has concentrated along I-4, and corporate tenants such as AAA and Mitsubishi Power have operations in the area. If your units service those buildings, their days are made of short hops between campuses, waits in loading zones and I-4 runs between calls. RDI Fleet, RDI Power’s fleet program, plans maintenance for exactly that duty cycle, and our technicians come from Brooksville to do the work where your vehicles park.
Light-duty diesels on the Lake Mary office corridor
RDI works on the light-duty diesels that service fleets rely on: Ford Super Duty with the Power Stroke, Ram with the Cummins, GM heavy-duty pickups with the Duramax, the Nissan Titan XD and Sprinter vans. Each has its own maintenance quirks, and a plan treats them that way. Every unit gets intervals from the manufacturer’s schedule or oil life monitor, adjusted for idle time, short trips and any towing, and each visit includes fuel filter and water separator service. On modern high-pressure common-rail fuel systems, water and dirt are expensive problems, and clean fuel filtration is the cheapest protection a fleet can buy.
Short hops between Lake Mary campuses and the DPF
Short trips and long idle periods are hard on modern diesel aftertreatment. The diesel particulate filter cleans itself by burning off soot during regeneration, and that needs exhaust heat a van creeping between office parks may never reach. The result is frequent active regenerations, interrupted regens and, eventually, a clogged filter and a derate on the way to an appointment. On an RDI Fleet plan, the technician checks soot load and regeneration history at each visit, inspects the DEF and EGR systems, and runs a parked regeneration when the system allows one. Drivers should report regen lights as soon as they see them; our article on DPF and regen problems lists the signs worth watching for.
Dealer-level diagnostics for Lake Mary Ford, Ram and GM units
When a light-duty diesel sets a code, the right software matters. RDI has Ford IDS for Ford trucks and WiTECH for Ram and other Stellantis vehicles, and its team includes a service advisor with 35 years as a Chevrolet dealership technician and a Ford specialist with more than 30 years at a Ford dealership. That depth shortens the path from a warning light to a root cause, which means fewer repeat visits for the same van and fewer parts replaced on a hunch. Fleet accounts also get priority service, so a unit that goes down between scheduled visits does not wait in line.
A Lake Mary fleet plan in four steps
- Talk. How many units, which models and engines, where they park overnight and how they are used during the day.
- Look. A technician inspects each unit at your lot and records its condition, its mileage and any open problems, so the first visits fix what is already wrong.
- Schedule. Intervals are set unit by unit, annual inspections are dated where they apply, and the calendar is built around the days each vehicle can be spared.
- Report. Every visit produces a digital inspection with photos and notes, building a history for each van and pickup that you can use at budget time.
Larger units fit the same plan. If your Lake Mary operation also runs a box truck, a tractor and trailer or a shuttle bus, those get their own intervals, and any of them rated above 10,001 pounds GVWR and used in interstate commerce get their annual DOT inspection booked with their PM.
What a Lake Mary yard visit looks like
The technician arrives with diagnostic tools and the supplies for the units that are due: oil and filters, fuel filters, coolant checks, belts and hoses, brake measurements, tire tread and pressure, battery and charging tests, lights and wipers, and a fault code check on every module the scan tool can reach. Firm, level pavement and access to keys are all the setup needed. Summer is the hardest season on vans that idle with the air conditioning running while a technician or a crew is inside a client’s building, so batteries, belts and the cooling system get extra attention before the heat arrives. Anything that needs a lift, a teardown or transmission work is scheduled into our Brooksville shop with you, around the days the vehicle can be out of service.
Lake Mary fleet coverage: warranty, priority and roadside
The fleet warranty on a Lake Mary account’s repairs runs 2 years or 24,000 miles. Accounts get 24/7 roadside assistance when a unit stops after hours on I-4, where FDOT counts nearly 15% trucks near Lake Mary, or on SR 417, where the share is about 20%.
