Fix LP gas detector false alarms in RVs. Covers trigger sources, sensor age, proper placement, and when to replace your propane detector.
Master your RV electrical system from house batteries to shore power. Covers 12V DC, 120V AC, inverters, and charging.
For F53 chassis work near Raleigh, try truck/fleet service centers rather than Ford dealers. Exhaust manifold and AC are standard automotive repairs any qualified shop can handle.
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.
Emergency start connects house batteries to chassis battery. If not working: verify house batteries are truly charged under load, listen for solenoid click when pressing button, check fuses, and verify correct activation procedure. Solenoid failure is common.

A Norcold N7LX.3F running more frequently than normal typically indicates cooling efficiency problems. Check door seals, thermostat calibration, and ensure proper ventilation around the cooling unit.
Dual purpose lithium batteries work for coach use but dedicated deep cycle lithium is better for house banks. Dual purpose compromises between starting and cycling. For RV house batteries, deep cycle LiFePO4 provides better value and cycle life.
