Newmar motorhomes on Freightliner chassis can experience rough rides due to improper ride height adjustment, incorrect air pressure settings, or suspension component wear. Most issues can be resolved through proper air bag calibration, shock absorber maintenance, and ride height adjustments.
Compare scan tools for Cummins 6.7 diesel engines in RVs. Covers professional and DIY options for diagnostics, codes, and DPF regeneration.
Protect your RV from freeze damage with this comprehensive winterization and de-winterization guide.
Keep your RV generator running reliably with this comprehensive maintenance and troubleshooting guide for Onan, Generac, and Cummins units.
Your chassis A/C cycling above 2800 RPM is likely caused by high head pressure from insufficient airflow at highway speeds, low refrigerant despite proper charge, or the PCM cutting A/C during high load conditions - this is normal protective behavior on Ford V10 engines.
Hard starting often fuel pressure bleed-down from check valve or injector. Test by cycling key to build pressure. Use gauge for definitive diagnosis.
Onan code 36 indicates a low fuel pressure issue in LP generators. This typically means a problem with the LP regulator, fuel solenoid, or gas line obstruction preventing proper fuel flow to the generator.
All headlights out with other lights working points to headlight relay or combination switch failure. Check and swap headlight relay first - if no change, the combination switch is likely failed. Common issue on late 90s Ford chassis.
Fully integrated GPS with dashcam and backup camera is rare. Garmin RV series accepts backup camera input. Consider quality separate components for best performance.
A 30-minute cycle time for your Whirlpool residential refrigerator in an RV at 65°F ambient temperature is slightly more frequent than ideal but not necessarily problematic. Normal cycle times range from 35-60 minutes depending on ambient temperature, door openings, and refrigerator load.
You can add a tachometer to your 2003 Itasca Spirit's Ford E-450 chassis by installing an aftermarket tach that connects to the ignition coil negative terminal or ECM. Autometer and VDO make excellent options that mount in a 2-1/16" gauge pod.
Front air bags not filling with air exhausting from height valve means the valve thinks chassis is too high. Check linkage connection and adjustment, or replace the stuck height control valve.
BlueDriver, OBDLink MX+, and FORScan all work with Ford E450 V10 motorhomes. FORScan offers the deepest Ford-specific diagnostics but has a learning curve.
Since your ECU board is unrepairable and Ford/RV dealers won't help, try specialized ECU rebuilders like Module Experts or Solo Automotive Electronics, or search for used units on car-part.com with your exact part number 7C3A-12A650-DSC.
1990 Tioga E-350 no start - check battery, fuel pump operation, spark in that order. Listen for fuel pump hum with key on. Check inertia switch reset button. Common failures are fuel pump relay and ignition module.
