Service FAQs

Consult owners manual and specific component manual for service intervals.

A good routine would be every 90 days.

A good multimeter, road flares or reflectors, a good flashlight (bright with extra batteries), extra engine belts, line pinch pliers to pinch off potential coolant leaks, small hand held screw gun with applicable bits.

First, you should weigh the coach on all axles then consult the tire manufacturer for the exact tire inflation. This will optimize ride and tire life.

The likely cause is your supplemental charging system (if equipped) is not operating correctly. If your vehicle is not so equipped, these devices are available as an add on component.

Two things to consider: First, it would be a good idea to top off the fuel tank and add a fuel stabilizing anti-algicide to the fuel to keep it in good condition. Make sure you run the engine and generator as well as the diesel aqua hot (if equipped) long enough to pull the treated fuel through the system. Second, we would recommend the addition of a dual bank battery charging system that can be installed and plugged into a standard wall outlet. The advantage of this is that you will not need to use the inverter for the purposes of maintaining the battery pack.

The most likely issues could be that you have not returned the “tank fill” valve to the city position, the pressure switch setting on the pump is incorrect, or the water tank is empty.

The first reason could be there is a leak in the airbag, the airbag fitting, or the airline feeding the bag on the affected (low) side of the unit. Another reason could be that the ride height valve, air distribution manifold or related fittings and hoses may have an air leak. If you are concerned about the unit leaning into something, drain the air system completely.

As the external air temperature drops, the heat pump’s efficiency lessens dramatically. As the temperature drops below 50 degrees outside, you will need to use the vehicle’s furnace for heat. At or below 40 degrees they are no longer effective.

First, check to see if soft ground is causing jacks to penetrate the surface. This can cause damage to the landing foot. The best way to avoid this is with the use of solid landing surfaces or the use of planks larger than the landing feet. This will help to spread the load. You may also have a leaky line. Check for obvious signs of leaks. The jack or fittings may also have a leak . The solenoid valve may possibly be defective as well.

At every opportunity. They are an amazing asset on hills as well as in town where stop and go traffic can heat brakes to the point of damage in minutes.

If it has air ride suspension and air brakes then most likely it does and it requires service. The air dryer is one of the most overworked and overlooked chassis components. When neglected, it can cause catastrophic failures of the brake and air suspension system.

There is mileage or time based intervals for service of nearly every component and they vary from system to system. A good rule would be to visually inspect and lube at every oil change and address issues as they become apparent.

The most common issues would likely be a restriction in the fuel system or the air cleaner. The primary and secondary fuel filters require replacement on a regular mileage interval. A good plan would be to replace them at every other oil change. The same thing applies to the air cleaner. A clogged air cleaner can significantly affect both mileage and power.

In all but the most extreme situations, an annual change of the ceramic or carbon filter should be sufficient.

Misadjusted ride height could be the culprit. It could also possibly be worn shocks. This situation can cause a rebounding effect as they are not sufficiently slowing the upward acceleration of the chassis, nor are they dampening properly on compression. The addition and upgrading to Koni FSD or Road King shocks can have a dramatic effect on the performance and handling of your coach. There are many aftermarket sway bars and related components to mitigate this drivability issue.
