2012 Trip
RPM - Every engine has a RPM range
that produces the most efficient torque
curve.
Fuel/Air Mixture - Even though the
engine is equipped with a turbocharger,
there is a limit to how much air can
be compressed into the combustion
chamber. Conversely there is a limit
to how much fuel can be injected to
produce the most efficient state of
combustion.
The drivetrain is more efficient when
temperatures remain stable during long grades.
IMPORTANT SAFETY TIP:
Turn on the hazard lights if road
speed decreases to the point where the
motorhome is moving significantly
under the posted speed. Use pullouts
if traffic is accumulating. Once in a
pullout, if there is sufficient clearance
for safety, idle the engine for a while
to allow the exhaust and the turbo
to cool. While these are cooling, the
transmission will also cool. Continually
monitor the gauges while waiting.
Descending a Grade:
Prepare to descend a grade at the crest of
the hill. Observe any signs indicating grade
angle and duration. The sign may suggest
maximum downhill speed according to Gross
Combined Weight (the combined weight of the
motorhome and a trailer/tow car). At the crest
of the hill, manually shift the transmission into
a lower gear. Do not allow the motorhome to
gain momentum before slowing down. Use
the exhaust brake to help maintain a slow, safe
downhill speed.


Road speed may still increase with the
exhaust brake is applied. The transmission
may automatically upshift to the next higher
gear to prevent engine over-speed. Apply
the service brakes using moderately heavy
pressure on the brake pedal to reduce speed
then manually downshift the transmission to
maintain a safe, slow speed. Do not pump the
brakes. This can result in a loss of air pressure.
Riding the brakes can cause the brakes to
overheat. Either method can result in loss of
brake effectiveness or even brake failure.
Night Driving:
Be well rested and alert. If necessary,
find a safe to stop and rest until ready
to continue.
Avoid using interior lights that create
a glare on the windshield and decrease
visibility.
Dim dash lights to a comfortable level
to reduce glare.
Extreme Heat/Hot Weather Conditions:
Frequently observe all gauges.
Variations from normal conditions
should be promptly evaluated.
Check tire pressure before traveling
in hot conditions. Tire air pressure
increases with heat. Do not let air out
of a hot tire. When the tires cool down
they will return to the correct/previous
tire pressure.
Pay extra attention to hoses and belts
that are more susceptible to fatigue in
extreme heat.

Winter and Cold Climate:
The motorhome should be prepared for
cold weather use.
Keep speeds slow and steady. Make
moves gradually and look further ahead
to increase reaction distance.
During cold weather tire air pressure
will decrease. Check tires and ensure
tires are at proper inflation pressure.
If road or weather conditions are
treacherous, find a safe place to stop
until conditions improve.
Avoid downshifting or using the
exhaust brake on wet or slippery
surfaces that can cause the drive wheels
to skid.
Wiper blades should be in good
condition. Fill the washer reservoir
with antifreeze formula window
washer fluid.
Use mirror heat to keep mirrors
clear.
Remove any ice build-up from
the entry step to avoid accidental
slipping.
Wet Conditions:
Worn or improperly inflated tires
can increase risk of hydroplaning.
Heavy rain or deep standing water can
cause brakes to apply unevenly or grab.
Refueling:
Truck stops are good refueling points.
Check overhead clearance before
pulling into the fuel island.
Be aware of concrete/steel posts
installed around fuel islands.
