HOLIDAY RAMBLER RV CLASS A DIESEL 2021 OWNER’S MANUAL 11
DEALER’S OBLIGATIONS
At the time of sale of your new recreation vehicle, your
dealer is expected to:
• Deliver your motorhome in the best condition
possible. Your vehicle must pass the dealer’s
detailed pre-delivery inspection, including all
systems tests. If the dealer identifies any issues
during the pre-delivery inspection, the dealer is
obligated to repair or replace any parts necessary
to correct the identified defects in material
or workmanship. As a part of the pre-delivery
inspection procedure, the dealer is responsible for
road-testing the motorhome, noting and correcting
any steering problems and setting correct tire
pressures before delivery. REV Recreation Group
will not be responsible for front end alignment after
this pre-delivery inspection has been performed.
• Provide orientation for use of the motorhome, its
systems, components, and operation.
• Make minor adjustments to your vehicle (such
as adjustments to the interior or exterior doors,
cabinet latches, TV antenna control, etc.) and
make those minor adjustments for a period of 90
days after delivery. Thereafter, such adjustments
are your responsibility as part of regular and proper
maintenance, unless the adjustment is required
as a direct result of repair or replacement of a
defective part that is covered under this warranty.
• Request that you read all warranty information
and explain any provision not clearly understood.
• Ensure that you receive your Owner’s Information
Warranty Packet. Your dealer can assist you in
completing the OEM warranty registration card
and locate any required component model or
serial numbers.
• Chassis registration will be completed by your
selling dealer at the time of purchase.
OWNER’S RESPONSIBILITY
It is important that you read and understand all
instructions and precautions before operating the
recreational vehicle. Even if you are an experienced
owner, we encourage you to thoroughly read this Owner’s
Information Warranty Packet. Familiarize yourself with
this limited warranty as there are components and
appliances that are excluded or warranted separately
by their individual manufacturer’s limited warranty.
As the owner, you are responsible for regular and
proper maintenance as described in the Owner’s
Information Warranty Packet. Regular and proper
maintenance will help prevent conditions arising from
neglect that are not covered by the limited warranty.
For example, dulling and fading of exterior paint can be
increased by prolonged exposure to extreme sunlight,
air pollutants, and excessive moisture. Regular
monthly washing and polishing of exterior surfaces
is the best insurance against surface deterioration
such as fading, yellowing, or chalking. It is your
responsibility and obligation to return your vehicle to
your dealer for repairs and services.
WARRANTY SERVICE PROCEDURES
To help ensure you receive the level of service you
expect and deserve, here are some suggestions we
would like to make.
If you need warranty service or warranty information,
please see the booklets and other documents included
in your Owner’s Information Warranty Packet. For
warranty service, you should return your motorhome
to the selling dealer. If that is not possible, you may
contact any other authorized REV Recreation Group
motorhome dealer. The REV Recreation Group Owner
Relations department can help you find a dealer in your
area. If you have any questions about the warranty or
what it does or does not cover, or need assistance
finding an authorized dealer, please contact REV
Recreation Group Owner Relations at the following
address or phone number:

to make warranty and repair decisions. To obtain
warranty service, you must (1) notify an authorized
dealer and send written notice to REV Recreation
Group within the applicable warranty period and (2)
within thirty (30) days of discovery of a defect in
material or workmanship. You will have up to thirty
(30) days after expiration of the warranty period to
notify an authorized dealer and REV Recreation Group
of a defect that occurred during the warranty period. If

SERVICE
If you are having warranty work performed, be sure you
have your vehicle information available to speed up your
service. Provide your dealer with a written list of the
motorhome problems or the specific repairs needed.
Keep a maintenance log of your vehicle’s service history
as this can be helpful when diagnosing and addressing
the current issue. If you had work done that is not in
your maintenance log, let the service advisor know. It
is important that you provide any vehicle repair history
to the dealer’s service personnel so they can better
understand the problem and assist you.
If you have a long list of service items that need
attention and you need your motorhome quickly,
discuss the situation with the service advisor, listing
the items in order of priority. This will help the service
department manage its time and will help get you back
on the road as quickly as possible. If required work is
not covered under the warranty, your dealer’s service
department can help you with getting the correct
service.
UNSATISFACTORY SERVICE
Once the work is complete, inspect the service or repair
job when you pick up your vehicle. Notify the dealer’s
service personnel immediately of any dissatisfaction.
Discuss any warranty related problems directly with
the manager or owner of the dealership, giving them an
opportunity to help the service department resolve the
matter for you. We sincerely believe that your dealer
and the factory representative will be able to solve
any problem that might arise. If, for some reason, a
problem is not handled to your satisfaction, we are
here to help.
If the dealer is unwilling or unable to resolve the issue
in a timely manner, immediately notify REV Recreation
Group by sending written notice detailing any alleged
unrepaired defect, or any other dissatisfaction
experienced with the motorhome. Giving the
manufacturer this direct notice, and opportunity to
cure, enables the manufacturer to supplement prior
efforts by its authorized dealers so any ongoing

Driving & Safety
SECTION THREE
DRIVING & SAFETY
Section Two contains information on driving tips,
emergency situations, towing, safety devices, weighing
the motorhome and tires.
INSPECTIONS
Differences between a passenger automobile and a
motorhome are significant. Always be aware of these
differences when traveling. The key to safely operating
a motorhome is inspection. Undetected problems
could cause problems on the road and may result in
lost time and increased repair costs. Several states
require a special license endorsement and motorhome
inspection prior to registration. Know and observe
the laws of the states in which the motorhome will be
traveling. Laws vary from state to state. A systematic
inspection conducted prior to moving the motorhome
can help ensure nothing is overlooked and will assist in
familiarizing the owner with the motorhome.
Perform a general inspection prior to moving the
motorhome. Examine the condition of the motorhome
and the surrounding area. Look “high and low” when
walking around the motorhome.
FAMILIARIZE YOURSELF
The location of the driver’s seat is higher and farther
to the left than most vehicles causing a different
perspective of the roadway. Use the outside mirrors to
gauge the center of the road and to check conditions
behind the motorhome. The dashboard may include
more gauges and controls than are normally found in
passenger automobiles. Become familiar with these
gauges and their indications before starting out.
MIRROR ADJUST
Adjust the mirrors prior to starting out. Have an
assistant help to ease the mirror adjustment process.
Course Adjustment:
• Tools needed: 5/32” Allen wrench, flat blade screw
driver and socket wrench.
• Adjust the driver seat to the travel position.
• Remove plug at the bottom of the arm.
• Use a socket wrench to loosen the bolt located at
the base of the arm (point A).
• Adjust the mirror for a
clear side view of the
motorhome.
• Tighten the bolt once
the proper adjustment
is made.
• Reinstall the plug.
• To adjust the “head”
of the mirror, loosen
the set screws located
below the mirror
shown as point B.
Adjust the head of the
mirror to the left or
right.
• Tighten set screws once the proper adjustment is
made.
• Repeat procedure for passenger side mirror.
Fine Adjustment:
• Use the mirror adjust switch to chose the left or
right mirror, and then use the arrow buttons to
make adjustments.
NOTE:
The motorhome has electronic data recording
devices that may record information about
direction, road speed, engine speed, brake
application, steering attitude or other vehicle
operating data. Data recording devices can be
present in engines, transmissions, ABS (Antilock
Brake Systems) or other systems affiliated with
operation of the vehicle. Information from data
recording devices can be examined in case of an
accident. Contact the component manufacturer to
learn more about these devices.

SAFETY SEAT BELTS
All occupants must be furnished with and use seat
belts while the motorhome is moving. The driver’s
seat, and all other seats designed to carry passengers
while the motorhome is in motion, are equipped with
safety seat belts. Do not occupy beds or seats that are
not equipped with a safety belt while the motorhome
is in motion. The driver’s seat must be locked in the
forward facing position while motorhome is in motion.
Seat belts are designed for individual use. Do not use a
seat belt for more than one person.
To fasten the seat belt, pull the belt out of the retractors
and insert the tab into the buckle; a click will sound
when the tab locks into the buckle. Seat belt lengths
automatically adjust to each occupants size and sitting
position. Do not route belts over armrest or under the
arm.
Child Passenger Safety
Child restraint requirements are determined by age
and weight. According to NHTSA (National Highway
Traffic Safety Administration), there are four stages
to child restraint safety. Go to: www.safercar.gov/
parents/RightSeat.htm
CHILD SEAT TETHERS (IF EQUIPPED)
Some child seat manufacturers recommend the use of
a top anchorage (tether) strap in addition to the lap
belt. Since a top anchorage (tether) strap can provide
additional security to a child seat, we recommend
using a tether whenever one is required or available.
The motorhome may be equipped with a child seat
top anchorage (tether) strap anchorage point in the
forward passenger seat location.
The anchorage hardware, if available, is located at the
lower rear of the passenger or secondary seat. A small
metal anchorage loop will be present which will allow
the tether strap hook to engage (see Illustration 1).
To use, with the seat
in position, drape the
tether strap over the
seat back and down
(see Illustration 2).
Attach the tether strap
hook to the tether
anchorage point and
tighten the strap
according to the child
seat manufacturer’s
instructions. Make
sure the strap is not twisted and that the forward
facing seat is always positioned upright and locked in
the forward facing position when the motorhome is in
motion.

WARNING:
Safety belts are supplied at affixed seating
positions. Do not occupy seats not equipped with
safety belts while the motorhome is in motion.
Seat belts must only be used on permanently
mounted seats. Do not use a single seat belt on
more than one person. Pilot and Co-pilot seats
must be locked in a forward facing position with
seat belts fastened while the motorhome is in
motion. Do not rotate the seat while in transit.
WARNING:
Refer to the manufacturer of the child seat for
installation guidelines. Adhere to all instructions,
cautions and warnings for proper securement of
the child safety seat or booster seat.

Driving & Safety
SECTION THREE
TIPS:
• Go to www.nhtsa.gov and choose “Child Safety Seat Information” from the menu or click on the child
passenger safety icon. The site includes child safety seat installation tips, product ratings, recalls and
other useful information.
• For more information about child safety seats, booster seats, inspection/fitting stations in your area,
seat belts, and other highway safety issues, call the DOT Vehicle Safety Hotline at: 1-888-327-4236.
• A certified child passenger safety technician can check your installation and answer questions. To find a
technician or an inspection station near you, go to www.nhtsa.gov, click on the child passenger safety icon,
and then click on the Fitting/Inspection Station link, or go to www.seatcheck.org.
Step 1:
For the best possible protection keep infants in the
back seat, in rear-facing child safety seats, as long
as possible up to the height or weight limit of the
particular seat. At a minimum, keep infants rear-
facing until a minimum of age 1 and at least 20
pounds.
Step 2:
When children outgrow their rear-facing seats (at a
minimum age 1 and at least 20 pounds) they should
ride in forward-facing child safety seats, in the back
seat, until they reach the upper weight or height
limit of the particular seat (usually around age 4
and 40 pounds).
Step 3:
Once children outgrow their forward-facing seats
(usually around age 4 and 40 pounds), they should
ride in booster seats, in the back seat, until the
vehicle seat belts fit properly. Seat belts fit properly
when the lap belt lays across the upper thighs and
the shoulder belt fits across the chest (usually at
age 8 or when they are 4’, 9” tall).
Step 4:
When children outgrow their booster seats, (usually
at age 8 or when they are 4’9” tall) they can use the
adult seat belt in the back seat, if it fits properly (lap
belt lays across the upper thighs and the shoulder
belt fits across the chest). All children under age 13
should ride in the back seat.
