Lakeland Highlands is counted in broader definitions of the Tampa Bay area, about 25 miles from the bay itself, yet it sits squarely in Polk County, between Lakeland’s city limits and Mulberry. A fleet based here can be dispatched west toward Tampa, north into Lakeland’s warehouse district or south on SR 37 toward Mulberry’s phosphate economy on any given day. RDI Fleet, RDI Power’s fleet program, builds a maintenance plan around that kind of variety, and the work happens at your yard.
A Lakeland Highlands base with routes in 3 directions
Mixed routes make maintenance harder to predict. A truck that alternates between interstate runs toward Tampa and short local jobs does not fit a simple mileage schedule. Neither does a pickup that idles for hours on a job site. Our first step is to look at each unit: what it does, how far it goes, how long it idles and what it carries. Intervals then follow the work, using miles for highway trucks, engine hours for units that idle or run equipment, and calendar dates for anything that sits.
Inside an RDI Fleet plan for Lakeland Highlands
The plan covers the whole operation rather than one truck at a time:
- Scheduled preventive maintenance. Oil and filters, fuel filters and water separators, air intake, cooling, brakes, tires, steering, suspension, batteries and a scan for stored codes.
- Annual DOT inspections. Federal rules require them for commercial vehicles with a GVWR of 10,001 pounds or more in interstate service, with the report kept for 14 months. We put each due date on the same calendar as that unit’s PM.
- Priority service. When a Lakeland Highlands fleet unit breaks between visits, it moves ahead in our schedule.
- Reporting. A digital vehicle inspection on every visit, with photos and notes, building into a service history for each unit.
No Polk County shop, so Lakeland Highlands maintenance comes to you
RDI Power’s only shop is in Brooksville. For a Lakeland Highlands fleet, that is less of a drawback than it sounds, because our technicians do most fleet work at the customer’s yard: inspections, PM, diagnostics and many repairs. Visits are scheduled ahead around the hours your Lakeland Highlands trucks are parked. When a job needs a bay, such as an engine overhaul or a transmission rebuild, we plan the trip to Brooksville with you so it lands when the truck can be spared.
Getting started with RDI Fleet in Lakeland Highlands
The first step is a conversation about your operation: the units, the work, where they park and what keeps going wrong. Next, a technician visits your Lakeland Highlands yard, lists every truck and trailer with its VIN, engine and mileage or hours, and notes what needs attention first. Intervals and inspection dates then go on a shared calendar.
Trailers are part of that inventory. An equipment trailer behind a contractor’s pickup, a flatbed or an enclosed hauler gets brakes, lights, wiring, tires and bearings checked at regular intervals, timed with the truck that tows it. If your Lakeland Highlands trucks regularly run west into Hillsborough County, the plan simply follows their mileage; the visits still happen at your home yard.
Repair or replace: what Lakeland Highlands reports show
Every visit produces a digital inspection for each unit, with photos and plain notes. After a year, those reports show something a shop invoice never does: which trucks are steady and which keep coming back with new problems. That is the information you need when an older truck needs an expensive repair and the question is whether to fix it or retire it. We give you a straight answer, backed by that truck’s own history.
Fleet warranty and 24/7 help for Lakeland Highlands units
Repairs on fleet accounts carry RDI Fleet’s 2-year / 24,000-mile warranty. RDI Fleet customers also get 24/7 roadside assistance, so a truck that stops on the Polk Parkway late on a Friday still has a technician who can see its records. Call (352) 433-3800 for both.
