Mail in Inverness Highlands South is addressed to Inverness, ZIP 34452, but this is its own unincorporated community: a residential stretch along the southern border of the city, with no city limits or downtown of its own. RDI Power has no shop here. Our only location is at 1665 Donto Way in Brooksville, about 21 road miles and 35 minutes from the middle of Inverness Highlands South, and our mobile technicians cover the distance when a truck should not.
Inverness Highlands South between the city and the forest
The community is easiest to understand by its edges. To the north is the city of Inverness, the Citrus County seat, with SR-44 and US-41 sharing Main Street. To the east, US-41 (Florida Avenue) runs north and south, and just past the community line sits Inverness Airport. To the west, the boundary follows the Withlacoochee State Forest, whose Citrus Tract covers 52,811 acres. Students here are zoned to Pleasant Grove Elementary or Inverness Primary, then Inverness Middle and Citrus High, with buses run by the school district’s Inverness transportation office.
That western edge is what sets the place apart. The Holder Mine, Mutual Mine and Tillis Hill camping areas, reached by forest roads numbered Trail 10, 13 and 16, all carry the same Inverness 34452 address as the neighborhoods next door. Holder Mine alone has 27 sites with electric service and water.
Pleasant Grove Road and Snow Memorial Highway to Brooksville
US-41 is the familiar road south out of Inverness, but from Inverness Highlands South the measured route to our shop takes the back road instead. Pleasant Grove Road, CR-581, runs south along the east side of the state forest. It follows the old SR-581 alignment and becomes Snow Memorial Highway, CR-481, at the Hernando County line, then runs on to Lake Lindsey before reaching Brooksville. Broad Street and Jefferson Street finish the trip. Allow about 35 minutes.
Before you set out on that route with a warning light on, call and describe it. A truck that stops partway down CR-481 is better served by a technician with a scan tool than by a guess.
Next door to the Inverness Airport business park
Just east of the community line, Citrus County is building out an 80-acre business park at Inverness Airport, aimed at aviation manufacturing and logistics, with Phase 2 construction under way in 2026. If your dump trucks, equipment haulers or service trucks are working that site, the shop and the mobile side both apply: a technician can come to the job, and bigger repairs can be planned into the Brooksville bays around the schedule.
Diesel warnings Inverness Highlands South owners should not wait on
A few symptoms are worth a call the day they show up, wherever the truck is parked.
Coolant loss with no puddle. When the reservoir keeps dropping and the driveway stays dry, the leak is internal, and the EGR cooler, the oil cooler and the head gasket are the usual suspects. Check the oil for a milky look and call before driving far.
Oil level going up. A dipstick reading that climbs means something is diluting the oil, usually fuel or coolant, and diluted oil stops protecting the bearings. Park it.
Frequent regens or a clogged filter message. The particulate filter is loading faster than it can clean itself, and something upstream, such as an injector, a boost leak or an EGR fault, is usually the reason.
Long cranking on a cool morning. Glow plugs on Power Stroke and Duramax engines, the grid heater on a Cummins, or tired batteries. We test before replacing.
Hard shifts or a transmission warning. On a truck that tows, engine and transmission complaints often travel together, and the scan tool sorts out which is which.
Our technicians are ASE certified, RDI Power is Caterpillar certified, and dealer-level software including Ford IDS and WiTECH lets us see what the factory tools see. Those tools cover every engine family we service: Power Stroke 6.0, 6.4, 6.7 and 7.3, Duramax, Cummins, Caterpillar, Detroit and Volvo. Each system we repair, from injection to aftertreatment, is described on our diesel service and repair page, and it all applies to Inverness Highlands South trucks.
Brooksville bay or a technician at the Withlacoochee State Forest edge
If the truck drives normally, bring it to Brooksville. If it does not, a mobile technician can come to a yard, a job site, a campground or the roadside with diagnostic tools and on-site repair capability, and confirm the problem before anything is towed. Either way, the work is documented in a digital inspection with photos you see before you approve the repair.
Pickup owners should read our Inverness Highlands South truck repair page next, and fleets have their own maintenance page listed alongside this one.
Diesel pushers near the Holder Mine campground
With 3 state forest camping areas sharing the community’s address, motorhomes deserve their own mention. A diesel pusher is a heavy truck underneath, and its Cummins or Caterpillar engine, Allison transmission, air brakes and suspension are squarely in our line of work. A coach that will not start or will not build air at a campsite can often be diagnosed right there by a mobile technician, and anything bigger is planned into the Brooksville bays. The details are on our Inverness Highlands South RV repair page.
For a wider view of the area: Floral City, a short drive south on US-41, is the closest Citrus County community to our shop; its Floral City diesel repair page covers that side.
Call (352) 433-3800 on any weekday between 7:00 AM and 4:00 PM, tell us where the truck is sitting, and we will help decide between the back road to Brooksville and a technician sent to the truck.
