Lukewarm water from your RV heater is typically caused by a failing heating element, sediment buildup, or thermostat issues. Most problems can be fixed by replacing the heating element, flushing the tank, or adjusting the thermostat.
Surge Guard 40250-RVC and 40350-RVC are interchangeable. Buzzing usually means loose connections - tighten all terminals. If buzzing persists with tight connections, the relay may be failing and unit needs replacement.
Yes, you can remove inverter/charger and install standalone battery charger. Much less expensive than replacement inverter. Check if inverter includes transfer switch - you may need to address that. IOTA or Progressive Dynamics chargers work well.
E-450 front squeak - identify when it occurs. Braking squeak is brakes. Over bumps is suspension. Check bushings, ball joints, and brake wear indicators.
Speed-dependent squeal from front driver side is likely brake caliper drag or wheel bearing. After driving until noise appears, feel wheel hub for heat - hot hub indicates caliper drag. Jack up and check for wheel bearing play. Compare to passenger side.
4x4 RV transmission filter service same as 2WD. Also service transfer case and front differential with correct fluids per manufacturer spec.
V10 lower hose replacement straightforward with coolant drain. Use quality hose and new clamps. Bleed air by running with heater on high.
Dometic RM2453 uses DSI direct spark ignition not a standing pilot or 2-stage burner. Burner ignites on demand when thermostat calls for cooling. Single stage operation runs full on or off.
Roadside diesel filter change is possible but priming is tricky. Carry spare filters and priming pump. Know your engine priming procedure. Prevention through quality fuel and regular changes is better approach.
Protect alternator from lithium battery high current draw using DC-DC charger for current limiting or temperature-controlled relay. DC-DC charger is best solution. Direct connection without protection risks alternator failure.
A disconnected ground wire in your transfer switch box is a serious safety issue that should be immediately reconnected to the ground bus bar. This appears to be a factory wiring oversight rather than an intentional configuration.
Boiling battery with sulfur smell means severe overcharging or internal short. Disconnect immediately - hydrogen gas is explosive. Battery must be replaced. Check converter/charger output voltage before installing new battery to prevent recurrence.
Texas DPS typically requires valid registration for road tests, but your expired CA tags and bonded title situation creates complications. You should call DPS directly before your Angleton appointment to avoid wasting time and potential legal issues.
Banks, UPFORD, and 5 Star V10 tunes all deliver similar improvements for RV use. Since you are happy with UPFORD, transfer your existing tune to the new coach. Transfer fee is more cost-effective than buying new tune from different provider.
Motoraid heat exchanger uses engine coolant for coach heating. Maintain coolant level and inspect hoses. Drain when winterizing.
