Fleetwood RV Motorhome Repair Service

Fleetwood coaches are built to travel, so we maintain them with brand-aware diagnostics, spec-correct parts, and clear communication. We service both coach and chassis under one roof, then road-test and document everything so your next trip starts confident.

Diagnostics & Common Repairs

A test-first workflow finds the root cause before parts go on.
What we solve most often:

  • Drivability & power: derates/regens, fuel delivery, boost/charge-air leaks, cooling on grades
  • Electrical (12V/120V): charging issues, parasitic draws, multiplex faults, bad grounds
  • HVAC & hydronic heat: roof A/C performance, Aqua-Hot/Hydro-Hot service, blower/zone control
  • Slide-outs & leveling: HWH/Lippert hydraulics, sensors, seals, ride-height & air-leak checks
  • Generator: Cummins/Onan hard starts, voltage/frequency stability, hour-based PM
  • Brakes/suspension/steering: air & hydraulic systems, hubs, shocks, alignment, vibrations
  • Plumbing & LP: pumps, water heater, tank sensors, fittings, winterization & leak tests

Chassis & Powertrains We Service

  • Diesel Class A: typically Freightliner chassis with Cummins power and Allison 3000/4000
  • Gas Class A: Ford F-53 with TorqShift; older V10 and current 7.3L platforms supported
  • Class C (where applicable): Ford and Chevy cutaways
    We coordinate engine, transmission, air system, and cooling work in one plan with a datalog + road test to confirm the fix.

Coach Systems & Upfits

  • Inverter/charger systems (Magnum, Victron, Xantrex), battery upgrades and load tests
  • Roof, cap, and seam inspections; sealant renewal; awning & slide-topper service
  • Cameras, TPMS, lighting, steps/doors, appliances; safety electronics and GFCI checks

Preventive Maintenance (PM) & Trip-Readiness

  • Chassis PM: engine oil/filters, fuel filtration (diesel), coolant test/exchange, belts/hoses, CAC/boost integrity, transmission/axle fluids, air dryer (where equipped)
  • Generator PM: oil, filters, mounts, output and frequency checks; run under load monthly
  • Coach PM: battery health, slide/leveling lube & calibrations, roof/awning inspection, tank sanitization, LP leak test
    Deliverables include VIN/coach-level documentation and a clear next-service plan.

Major Repairs — Engine

Planned around your travel calendar with failure confirmation up front.

  • Verification: compression/leak-down, injector balance/return, fuel pressure & restriction, boost/CAC integrity, oil analysis, cooling pressure/flow
  • In-frame/Out-of-frame overhauls: head service, liners/pistons (diesel), bearings, oil pump, timing components, full gasket/seal kits, overhead set to spec
  • Air & fuel systems: turbo/VGT checks, charge-air piping/clamps, high-pressure fuel testing and components
  • Aftertreatment integration (if equipped): DPF cleaning/replacement, DOC/DEF checks, NOx/temp sensor calibration, EGR diagnostics to prevent post-repair regens/derates
  • Cooling restoration: radiator/CAC replacement, water pump, thermostats, fan hub/clutch, hoses/surge tank
  • Validation: hot/cold starts, no-load & on-grade tests, leak/boost checks, and data logs with take-home records

Major Repairs — Transmission

Support for Allison 3000/4000 and TorqShift platforms.

  • Diagnostics first: TCM codes, adaptations, line-pressure tests, harness/ground checks, cooler flow & temperature trend review
  • Service & repair: fluid/filters to spec, external seals/leaks, sensors, range switch, wiring/connectors, cooler & lines
  • Rebuilds & replacements: clutch packs, torque converter, valve body/solenoids; or approved reman when downtime or economics favor a swap
  • Calibrations & learn: resets/adaptations, shift-quality verification, PTO checks (if equipped)
  • Validation: temperature-controlled road test, no-drip recheck, and printed report with next-service interval/fluid spec

Fleetwood RV Service FAQs

Quick answers about Fleetwood RV service at Britt’s Diesel—coach + chassis coverage (Freightliner/F-53), Cummins/Allison/TorqShift support, test-first diagnostics, PM before long trips, and major engine/trans repairs.

Bounder, Southwind, Pace Arrow, Discovery, Excursion, Revolution, and more—on Freightliner (diesel) and Ford F-53 (gas) chassis. We support Cummins + Allison and TorqShift, plus Cummins/Onan generators.

We run one work order with parallel tasks: a chassis tech handles engine/trans/brakes while a coach tech tackles slides/leveling (HWH/Lippert), HVAC, electrical, and plumbing. Parts are pre-staged after diagnostics, approvals via text/email, and we finish with one road test + leak/functional recheck.

A test-first workflow: live data logs, fuel pressure/restriction, boost/CAC smoke testing, cooling performance checks, and 12V/120V voltage-drop/ground tests and multiplex review—to fix root cause, not just clear codes.

Yes. Engines: failure confirmation, in-frame/out-of-frame overhauls, turbo/VGT, charge-air, cooling, and aftertreatment integration. Transmissions: Allison 3000/4000 and TorqShift diagnostics, service, rebuilds/reman swaps, calibrations/adaptives, and cooler/line repairs.

Chassis PM (oil/fuel filters, coolant test/exchange, belts/hoses, CAC integrity, trans/axle fluids, brakes/suspension, tires/TPMS), generator PM (run under load monthly), and coach PM (battery load test, inverter settings, slide/leveling lube, roof/awning inspection, LP leak test, tank sanitization). Booking 1–2 weeks ahead is ideal.
