Weighing The Motorhome; Weight Terms - Holiday Rambler Imperial 2008 Owner's Manual

DRIVING & SAFETY — 2
NOTE:
Loosen and tighten lug nuts in sequence
(see illustration). Sequence tighten to
50 ft. lbs. first, then sequence tighten to
500 ft. lbs. Over-tightening can cause
distortion.

WARNING:
Never use wheels or lug nuts different
than the original equipment as
this could damage the wheel or the
mounting system. Damage to the wheel
or mounting system could cause a wheel
to come off while the motorhome is in
motion.
Front Wheels:
Slide the front wheel over the studs. Use
caution to avoid damaging stud threads. Snug
the nuts in sequence. When all nuts have
been seated, tighten the nuts to 500 ft. lbs. in
sequence (as shown in illustration).

Dual Rear Wheels:
Slide the inner dual wheel over the studs. Use
caution to avoid damaging threads. Align the
handholds for valve access and slide the outer
dual wheel over the studs, again using caution
to avoid damaging the stud threads. When all
nuts are seated, tighten the nuts to 500 ft. lbs. in
sequence (as in illustration).
The hub mount wheels use two-piece fl ange
cap nuts for both front and rear applications. No
inner cap nuts are required.
Torque the Nuts Properly:
Tighten the wheel nuts to the
recommended lug nut torque. DO NOT
over-tighten.
Maintain the nut torque at the
recommended level through planned
periodic checks or at 10,000 mile
intervals, whichever comes fi rst.
If air wrenches are used, they must be
periodically calibrated for the proper
torque output. Use a torque wrench to
check air wrench output and adjust line
pressure for the correct torque.

WEIGHING THE MOTORHOME

Proper weight distribution, load management
and operating within established limitations will
aid in safe and enjoyable travel. The information
in this section outlines guidelines and provides
worksheets for weighing procedures.

Proper weight distribution and load
management is an individual responsibility.
In order to correctly manage load and weight
distribution, more than one weight measurement
will be required. Each wheel position must be
weighed to accurately determine the weight
placed on each wheel position for proper
weight computations. The entire process of
weight management begins with the Gross
Vehicle Weight Rating as listed on the Federal
Certifi cation Label. This weight cannot be
exceeded.
CAUTION:
Most States limit the amount of weight
carried by any single axle position. It
is the responsibility of the operator to
know the legal weight limit of the State
in which they travel.

Weight Terms

Numerous Federal, State and local governments
mandate weight limits. Understanding the
terminology and performing proper weighing
procedure will help eliminate confusion. It is
important to weigh the motorhome to calculate
Cargo Carrying Capacity (CCC) and ensure no
axle is overloaded.
