Engine Platforms
We repair diesel RVs and motorhomes on-site — at your campground, RV resort, rest stop, or on the shoulder of I-95. Class A diesel pushers, Class C diesel chassis, anything with a diesel engine that's supposed to get you where you're going. We focus on the mechanical side — the engine, drivetrain, brakes, generator, and chassis systems that make your RV move and stop. Cummins ISB, ISL, and ISC engines. Ford, Freightliner, and Mercedes Sprinter chassis. If it's diesel and it's broken, we fix it where it sits.

Know the Warning Signs
Symptoms That Mean Your RV Needs Repair
Check engine light
On a diesel RV, this often points to aftertreatment issues (DPF/DEF), turbo problems, or sensor faults. Newer diesel pushers with emissions systems are especially prone to codes after sitting in storage or running short trips around town.
Overheating while climbing bridges or sitting in traffic
Florida is flat, but the 17th Street Causeway, the Okeechobee bridge, and stop-and-go on I-95 load the engine hard. If your temp gauge climbs in these situations, you likely have a cooling system problem — low coolant, a failing water pump, a plugged radiator, or a bad thermostat.
Generator won't start or shuts down under load
Your Onan or Cummins genset cranks but won't fire, or it starts fine but dies when you turn on the AC. This usually comes down to fuel delivery issues, a clogged carburetor (gas gensets) or injector problems (diesel gensets), or a faulty control board.
Brakes feel soft or spongy
Whether your RV runs air brakes or hydraulic brakes, soft pedal feel means something is wrong. Air system leaks, worn brake linings, or hydraulic fluid loss all compromise stopping power — and your RV weighs 20,000 to 40,000 pounds. Don't gamble on this one.
Air suspension sagging on one side
A leaking air bag, a failed compressor, or a stuck leveling valve causes uneven ride height. Besides looking wrong, this puts uneven stress on tires, axles, and frame components.
Transmission shifting rough or delayed
Hard shifts, late engagement, or slipping between gears means the transmission needs attention. On Allison automatics (common in Class A pushers), this can be a fluid issue, a solenoid problem, or internal wear.
Root Cause Analysis
Common Causes of RV Breakdowns in Florida
Diesel engines are built for a million miles — but these conditions accelerate wear and cause premature failure.
Overheating from sitting in storage during summer
An RV that sits from May to October in a South Florida storage lot bakes in 130-degree surface temperatures. Coolant degrades, belts dry-crack, hoses get brittle, and thermostats stick. The first long drive of the season overloads a cooling system that's been slowly deteriorating all summer.
Battery death from parasitic draw during storage
RVs have multiple systems that draw small amounts of power even when everything is "off" — LP detectors, stereo memory, control boards. Over months of storage, these parasitic draws kill the chassis batteries and house batteries. Dead batteries also mean no generator start.
Tire failures from UV exposure and heat
Florida sun destroys tires whether you drive on them or not. UV breaks down the rubber compounds, and heat accelerates the process. An RV tire that looks fine can have internal sidewall degradation that leads to a blowout at highway speed. Age matters more than tread depth on RV tires.
Generator fuel system issues from ethanol fuel sitting too long
Ethanol-blend gasoline absorbs moisture and breaks down within 30 to 60 days. Gas generators that sit with untreated fuel develop gummed-up carburetors and corroded fuel system components. Diesel generators fare better, but stale diesel still grows algae in Florida's humidity.
Aftertreatment problems from short-trip and low-speed operation
Newer diesel RVs with DPF systems need sustained highway speeds to regenerate the particulate filter. RV owners who only drive short distances — campground to grocery store and back — never get the exhaust hot enough for a regen cycle. The DPF clogs, the dash lights up, and eventually the engine goes into derate.
How We Work
Our Diagnostic Process
We don't guess at parts — we diagnose the root cause before turning a single wrench.
Listen to you first
You know your RV better than anyone. When did the problem start? What were you doing when it happened? Did anything change recently? Your observations point us in the right direction faster than any scan tool.
Chassis and engine scan
We connect to the engine ECM and chassis systems with diagnostic software. On Cummins-powered coaches, we use Cummins INSITE to pull fault codes, run cylinder cutout tests, and check system parameters. On Freightliner and Sprinter chassis, we access the chassis controller and ABS systems.
Generator diagnostics
If the genset is the issue, we diagnose it as a separate system. We check fuel supply, air intake, exhaust, control board fault codes, and load-test the output. Generator problems are often fuel-related in Florida due to ethanol and storage issues.
Visual and mechanical inspection
We physically inspect the engine bay, undercarriage, brake components, air system, and cooling system. Leaks, corrosion, cracked belts, rodent damage, and loose connections all show up on a hands-on inspection.
Explain what we find in plain language
We tell you exactly what's wrong, what caused it, what it takes to fix it, and what your options are. No jargon, no pressure, no upselling.
Our Standards
Our Repair Approach
Clear communication
We explain what we're doing and why. If there are multiple repair options, we lay them out with honest pros and cons so you can make an informed decision. We don't assume you know what a DPF regen is or why your Allison is slipping.
OEM-spec parts
We use parts that meet or exceed original equipment specifications. Your Cummins ISL gets Cummins-spec filters and fluids. Your Freightliner chassis gets the right brake components. We don't cut corners on a rig that carries your family.
We come to you
RV park, campground, storage lot, rest stop, Walmart parking lot, or the shoulder of the highway. You don't need to figure out how to get a 40-foot motorhome to a shop. We bring the shop to you.
Respect for your rig
We use fender covers, clean up after ourselves, and treat your coach like it matters. Because it does.
☀️ South Florida Conditions
Florida-Specific Considerations
Running a diesel engine in South Florida is different from running one anywhere else. Year-round heat, humidity, and salt air create unique challenges our technicians are specifically trained for.
Snowbird season creates massive RV population
From October through April, thousands of RVs roll into Palm Beach County, Broward County, and points south. KOAs, state parks like Jonathan Dickinson and John Prince, and RV resorts throughout the area fill up. That means a lot of diesel motorhomes that just drove 1,000 to 2,000 miles from the Northeast or Midwest — and some of them arrive with problems.
Summer storage is brutal
RVs that sit in South Florida from May to October endure relentless heat, UV exposure, and afternoon thunderstorm humidity cycles. Batteries die, tires degrade from the inside out, belts and hoses crack, coolant breaks down, and rodents move in and chew wiring harnesses. The first start after summer storage often reveals several problems at once.
Salt air corrodes underbody components
RVs parked or driven along A1A, near the Intracoastal, or anywhere within a few miles of the coast are exposed to salt air that corrodes brake lines, electrical connectors, chassis fasteners, and exhaust components. Underbody corrosion is a real problem on rigs that spend winters near the beach.
Florida's flat terrain is easy on drivetrains but the heat is brutal on cooling systems
You won't blow a turbo climbing a mountain pass in Florida, but sustained 95-degree ambient temperatures with full AC load push cooling systems to their limits. An RV towing a car through summer traffic on I-95 is working harder than most owners realize.
