About This Manual
The purpose of this manual is to serve as guide to normal
operation, safety, care, and maintenance of your recreation
vehicle (RV). The information in this manual is accurate at the
time of publication but is subject to change without notice.
Photographs, drawings, components, and systems described
may not represent what is actually in your RV due to ongoing

any way to supplement, modify, or alter the terms and condi-
tions of your Limited Base and Structural Warranties, or any

Procedures outlined in this guide are typical for normal op-
erating conditions. You are responsible for the safe operation
and use of your RV, and we have tried to include information
to assist you. There are occasional tips to help you enjoy the
recreational lifestyle; however, this guide is not intended to

Introduction
Owner Information Package
The Owner Information Package contains the manuals and
registration cards for several individual components of your
new Momentum Fifth Wheel (FW).
• It is critical that you register and activate each component
warranty within the prescribed time limits to avoid loss of
warranty coverage.
• Some component manufacturers oer warranties beyond
the Grand Design Limited Base and Structural Warranties.
• Other components are warranted separately and exclu-
sively by the individual component manufacturer, and are
therefore excluded from our Limited Base and Structural
Warranties.
It is important that you read and understand the informa-
tion in this manual and your Owner Information Package
before using your RV.
Manufacturing Certification
Grand Design RV recreation vehicles are constructed to the
thorough safety and construction standards established by the
Recreational Vehicle Industry Association (RVIA). Frequent and
random audits are conducted by RVIA and Transport Canada to
confirm compliance to U.S. (RVIA) and (if applicable) Canadian
(CSA) standards.
Either a RVIA or CSA label is axed to the sidewall next to the
entry door to confirm your RV has been constructed to these
exacting standards.
This NOTE symbol is used to
identify special attention items,
like useful tips, reminders or
maintenance items.
This manual and the
owner information
package should
be considered a
permanent part of the RV.
If the RV is sold, both
should remain with the RV
for the next owner.

Introduction
Safety Precautions
Nothing is more important than the personal safety of you, your
family and others. Safety encompasses several areas relat-
ed to the RV experience. This includes driving/towing safety,
occupant safety, operational safety, environmental safety, and
more. Any time you are dealing with carbon monoxide produc-
ing appliances, propane gas, electricity and other hazards it
is critical that safety become your number one priority in and
around your recreational vehicle.
Various safety
and information
labels are attached
to surfaces both
inside and outside your RV.
These labels are permanent
and should not be removed
or relocated for any reason.
The Safety Alert Symbol is used to
alert you to potential personal injury
hazards. It is imperative that you read,
understand and abide by these safety
alerts and messages to avoid possible
personal injury or death.
DANGER indicates a
hazardous situation which,
if not avoided, will result
in death or serious injury.
DANGER
CAUTION indicates a
hazardous situation which,
if not avoided, could result
in minor or moderate injury.

and how to operate all systems and components.
3. Review with you, and explain the provisions of the
Limited Base Warranty and Limited Structural Warranty.
4. Send your completed Warranty Registration and
New Vehicle PDI Check List to Grand Design RV.

your RV, and its (separately warranted) components,
including repairs NOT under warranty.

Owner’s Responsibilities
As the owner, you are responsible for the regular care and
proper maintenance of your RV. Proper maintenance will help
avoid situations where the Limited Base Warranty and Limited
Structural Warranty will not cover items due to neglect. You
need to perform maintenance services in accordance with this
manual and the corresponding manufacturer instructions for
the components included in your RV.
It is also your responsibility and obligation to return the RV to
an authorized dealer for any warranty repairs and service that
may be required. Your dealer is responsible for proper service
prior to delivery, and has a continued interest in your satisfac-
tion. Therefore, we recommend warranty and maintenance
services be performed by your Grand Design RV dealer.
As with your other personal belongings, it is important to
protect yourself and others with insurance coverage. Your
insurance agent can assist you in obtaining the appropriate
insurance coverage for personal liability, theft, collision, and
property damage, etc.

unauthorized or
improper warranty repairs,

Obtaining Warranty Service
Warranty service must be obtained:
• WITHIN a reasonable time after the discovery
of a defect, and
• BEFORE the applicable warranty period expires.
To help your dealer provide you the best level of service,
please do the following:

you plan to use your RV. Your dealer may need some time to
get you in their schedule. Most service departments are busi-
est on Mondays, Fridays and before holidays.

Past repairs and maintenance records may help the service
technician diagnose a current issue.
Make a list
Provide the dealer a prioritized list of all repairs needed. If you
need your RV returned by a specific date, discuss this with the
dealer’s service management. A second appointment may be
required to complete lower priority list items or if parts need to
be ordered.
While waiting
If possible, drop o your RV. Usually, customers cannot watch
as repair work is performed. insurance companies may even
require that customers not be allowed in the service area.
Inspect the work performed
Inspect all repairs thoroughly. Notify the dealer’s service
manager of any dissatisfaction right away.
• If you cannot immediately return your RV for repair,
make an appointment to return as soon as possible.
• If a problem re-occurs after leaving the dealership,
contact the dealer’s service manager and Grand Design
RV Customer Support, to quickly resolve the issue.
