Inverness Highlands South is mostly homes, but its eastern edge meets Inverness Airport, where Citrus County is building an 80-acre business park for aviation manufacturing and logistics. Any heavy truck working that project, or parked in the neighborhoods beside it, is about 21 road miles from the heavy bays at RDI Power, 1665 Donto Way in Brooksville.
Heavy trucks around the Inverness Airport business park site
Phase 2 construction on the business park started in 2026, with the county planning a 3,500-foot taxiway extension alongside it. If your dump trucks, lowboys, mixers or service trucks are on that job, they live the hard life of a construction truck: short loaded runs, long idle periods and rough ground around the site. That duty cycle has a pattern of failures, and the aftertreatment system usually shows up first. Idling and stop-start hauling keep the exhaust too cool, the particulate filter collects soot quicker than regeneration can burn it off, and EGR valves gum up until the engine derates. Clearing the code without fixing the cause only sets the truck up to fail again.
Our article on DPF and regen problems explains why the cycle starts and how it gets broken.
Class 8 faults worth a call from Inverness Highlands South
Some heavy-truck problems can wait for a planned shop visit. These usually cannot:
- Air pressure that will not build or will not hold. A cracked line, a leaking valve, a failing compressor or a governor out of adjustment. Driving on low air is not an option.
- A coolant temperature that climbs under load. On a heavy engine that usually starts with airflow, meaning a packed radiator or charge air cooler or a fan clutch that will not engage, before it becomes a coolant problem.
- A no-start or a starter that clicks. Batteries, cables, a ground at the frame or the starter itself, often fixable on site.
- Warning lights with power loss. Sensors, wiring, injectors or aftertreatment, sorted out with a scan tool before parts are ordered.
Electrical faults deserve a mention too. On a heavy truck, chafed wiring along the frame rails, corroded connectors and failing grounds can produce a string of unrelated warning lights, or modules that stop talking to each other on the data link. Tracing those takes patience and a wiring diagram, not a parts cannon.
RDI Power is Caterpillar certified, so older Cat engines, including the 3406, are rebuilds we take on rather than send away. On the fuel side, we use Alliant Power and Bosch diesel components.
A heavy tow from Inverness Highlands South: CR-581 or US-41
The measured route from the middle of the community to our shop runs south on Pleasant Grove Road, which becomes Snow Memorial Highway at the county line, then into Brooksville. US-41 runs just east of the community as the other way south. Which road a wrecker takes is the tow operator’s call. What we can do is make the trip worth it: call (352) 433-3800 before the truck is hooked up, and if a mobile technician in Inverness Highlands South can confirm the fault first, the truck arrives with a diagnosis and a plan.
In the shop, every heavy truck gets a digital inspection with photos of the repair and the condition of brakes, tires and suspension, so nothing comes as a surprise later. Heavy-duty labor for Inverness Highlands South owners carries the same 3-year, 36,000-mile warranty as our light duty work. The full scope is on our semi and heavy-duty truck repair page, and trucks based on the north side of the city are covered on our Inverness semi truck repair page.
