Fuller Heights covers about 5.2 square miles and had 10,467 residents in 2020. The Census Bureau first listed it as a census-designated place in 2010, and its mail goes to the 33860 ZIP code it shares with Mulberry. The roads around it carry serious freight: within about 2 miles of the community’s center, FDOT counts thousands of trucks a day. RDI Power has no shop in Fuller Heights. When a diesel stops here, a technician drives out from Brooksville.
SR 60 traffic near Fuller Heights
SR 60 is the big east to west road in this part of Polk. It leads west toward Brandon and east toward Bartow and Lake Wales. FDOT’s 2025 count on the busiest segment near Fuller Heights is about 23,000 vehicles a day, and 4,531 of them, 19.7%, are trucks. With that many heavy vehicles, a stopped truck on the shoulder has very little margin. Move it as far over as it will go, use the hazards and triangles, and stand well away from the lane while you call.
SR 37 and Imperial Lakes Boulevard around Fuller Heights
SR 37 runs north toward Lakeland and south toward Bradley Junction. Its segment between Shimmering Drive and CR 540A carries about 40,000 vehicles a day in FDOT’s 2025 count, around 2,320 of them trucks. Imperial Lakes Boulevard is one of the local roads into the community. For any of these, the most helpful thing to tell us is the nearest intersection or a business sign, plus which direction the truck was headed.
Fuller Heights repairs that do not need a tow
Many breakdowns are quick work once the cause is known. A Fuller Heights call might turn out to be:
- A Power Stroke that cranks but will not fire because of a failed fuel filter or water in the fuel
- A medium-duty truck with a dead alternator and batteries drained flat trying to make up for it
- A tractor with a leaking air line or a failed brake chamber
- A broken connector or chafed wire that set a warning light and cut power
The technician scans first, tests the suspect part, and then repairs it. For each Fuller Heights repair, you get a digital vehicle inspection with photos and notes.
Pickups and light trucks around Fuller Heights
A diesel pickup that quits near Fuller Heights is just as stuck as a tractor. On Power Stroke and Duramax engines, a hard start on a cool morning can point to glow plugs, which newer versions of both engines do use. Rough running, smoke or a misfire code may point to an injector, and RDI is a Bosch dealer and works with Alliant Power fuel injection, so that diagnosis is done properly before any part is ordered. For Cummins-powered Ram trucks, WiTECH gives the technician dealer-level access.
Before calling from Fuller Heights
Have the truck’s year, make and engine handy, and know which road you are on, SR 60, SR 37 or a local street, plus the nearest intersection. Describe the last few minutes before it stopped: a noise, a smell, a gauge that moved, a light that came on. If you can read a fault code on the dash, write it down, and tell us whether the truck is loaded. A photo of any leak under the truck, taken from a safe spot, helps too.
