About This Manual
The purpose of this manual is to serve as guide to describe
normal operation, safety, care and maintenance of your rec-
reation vehicle (RV). Information in this manual is subject to
change without notice and represents information relevant at
the time this version was published. The photographs, draw-
ings, components and systems described may not represent
what is actually in your RV due to ongoing upgrades and
improvements. There is nothing in this manual that creates
any warranty, express or implied. Information in this manual is
not meant in any way to supplement, modify or alter the terms
and conditions of your Limited Base and Structural Warran-
ties or any component manufacturer warranties.
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

nent manufacturer manuals and registrations. Some com-

tural Warranties, and are warranted separately and exclu-
sively by the individual component manufacturer. Activation

Introduction
of each component warranty is critical, so it is important you
register within the prescribed time limits to avoid loss of war-
ranty coverage.
It is important you read and understand the information in this
manual and your Owner’s Information Package before using
your RV.
Manufacturing Certification
Grand Design recreation vehicles are subject to frequent
and random audits to confirm our RV’s are constructed to
the thorough safety and manufacturing codes, standards and
regulations established by the Recreation Vehicle Industry
Association (RVIA) and Transport Canada (CSA).
Either a RVIA or CSA label is affixed to the sidewall next to
the entry door to confirm your RV has been constructed to
these exacting codes and standards. RV’s built for sale in
Canada may differ to conform to Canadian Codes.
The Vehicle Identification Number
The 17-digit vehicle identification number (VIN) is listed on
the Federal Certification label and is stamped on a perma-
nently affixed metal tag attached to the pin box. A breakdown

Safety Precautions
Nothing is more important than the personal safety of you,
your family and others. Safety encompasses several areas re-
lated to the RV experience. This includes driving/towing safe-
ty, occupant safety, operational safety, environmental safety,
and more. Any time you are dealing with carbon monoxide
producing appliances, propane gas, electricity and other haz-
ards it is critical that safety become your number one priority
in and around your recreational vehicle.
Safety alert symbols and messages are used throughout your
vehicle and in this manual:

REPORTING SAFETY DEFECTS
United States
If you believe that your vehicle has a defect which could
cause a crash or could cause injury or death, you should im-
mediately inform the National Highway Traffic Safety Admin-
istration (NHTSA) in addition to notifying Grand Design RV. If
NHTSA receives similar complaints, it may open an investi-
gation, and if it finds that a safety defect exists in a group of
vehicles, it may order a recall and remedy campaign. How-
ever, NHTSA cannot become involved in individual problems
between you, your dealer or Grand Design RV.
To contact NHTSA, you may either call the Vehicle Safety
Hotline toll-free at 1-888-327-4236 (TTY: 1-800-424-9153); go

Service & Warranty
SERVICE & WARRANTY
Dealer’s Responsibilities
At the time of sale of the new RV, your dealer is expected to:
1. Deliver your RV in the best condition possible. Your RV
must pass the dealer’s Pre-Delivery Inspection (PDI),
which includes all system tests.
2. Provide orientation and familiarize the customer with
the operation of all systems and components of the
new RV.
3. Explain and review the provisions of the Limited Base
Warranty and Limited Structural Warranty to the cus-
tomer.
4. Ensure the customer receives a complete Owner In-
formation Package. Assist the customer in completing
all necessary warranty registrations, including locating
model and serial numbers as needed.
5. Instruct the customer on how to receive local and out
of town service on the RV and its separately warranted
components, whether in or out of warranty.
6. Service all Grand Design RV products.
7. Complete and return the “Warranty Registration and
New Vehicle Pre-Delivery Inspection Check List” form
within thirty (30) days from the date of delivery to
Grand Design RV to activate your applicable warranty
coverage.
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.
As the owner, it is 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

11
Service & Warranty
in your satisfaction. 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, prop-
erty damage, etc.
Obtaining Warranty Service
Service must be obtained within a reasonable time after dis-
covery of the defect and prior to the applicable warranty expi-
ration period. To help ensure your dealer provides the level of
service you expect, here are some suggestions:
Call ahead — Do not wait until you are ready to use your RV,
as your dealer may not be able to schedule it in immediately.
Generally, the service department is busiest on Mondays,
Fridays and before the holidays.
Be prepared — Have your warranty paperwork available,
and provide the service center with any past repair history as
it may assist the dealer technician in diagnosing the current
issue.
Make a list — Provide a written list of repairs needed in spe-
cific order of priority, and be reasonable with repair expecta-
tions. If you need your RV returned by a specific time, discuss
the situation with the dealer’s service management as a sec-
ond appointment may be necessary for work not completed or
parts that may need ordered.
While waiting — Drop your RV off if possible. Do not be
surprised if told you cannot watch work being done. Some
insurance requirements forbid admission of customers to the
service area.
Inspect the work performed — After a repair is performed
inspect it thoroughly. Notify the dealer’s service management
immediately of any dissatisfaction. If you cannot return your
RV immediately for repair, make an appointment as soon as
possible. In the event the issue should re-occur after you have
left the dealership, contact the repair center and Grand De-
sign RV Customer Service as soon as possible, so the situa-
tion can be resolved expediently.

12
Service & Warranty
Obtaining Emergency Warranty Repair
A roadside emergency can happen at any time, whether
your RV is new or old. If you are traveling, using the following
guidelines can help get you back on the road faster.
1. Use the “Dealer Locator” on our website to locate the
nearest authorized repair center.
2. If you cannot locate an authorized dealer near you, ask
the campground staff for referrals or check the local
telephone yellow pages. Or contact Grand Design RV
Customer Service or your selling dealer for assistance
in locating a repair facility.
a. Contact the RV repair facility to discuss your situa-
tion and make an appointment. Ask how their billing
will be handled. They may choose to bill Grand
Design RV directly; otherwise, you are expected to
pay them.
b. Have the RV repair facility inspect your RV. Either
they or you must call Grand Design RV Customer
Service to discuss applicable warranty coverage
prior to any repair work being performed.
c. Grand Design RV Customer Service will issue an
authorization number upon warranty repair approv-
al and advise if any original parts must be returned.
d. After the authorization number has been issued, the
repair center may begin actual repair on your RV.
e. Inspect the completed repair work thoroughly. If you
are not satisfied, communicate that to the RV repair
facility management. Make sure you are satisfied
with the repair before you pay or leave the premis-
es.
f. For reimbursement, either you or the RV repair
facility must send a copy of your itemized repair
bill and all requested return parts by UPS (regular
ground, freight pre-paid) to Grand Design RV within
60-days of the completed repair date. To expedite
processing your warranty claim, include your name,
address, phone number, RV 17-digit VIN and autho-
rization number. If returning parts, include a copy of
your freight bill.

13
Service & Warranty
Obtaining Weekend or After Business Hours Emergency Repair
Assistance
If an authorized Grand Design RV dealer is not located near-
by, contact your selling dealer for assistance. If your dealer is
closed, check with the campground staff or telephone yellow
pages for an RV repair facility. Have the item repaired and
contact Grand Design RV Customer Service immediately the
following business day.
An important Note about Alterations and Warranties
Installations or alterations to the original equipment vehicle
as distributed by Grand Design RV are not covered by the
Limited Base and Structural Warranties. The special body
company, assembler, equipment installer or upfitter is sole-
ly responsible for warranties on the body or equipment and
any alterations (or any effect of the alterations) to any of the
parts, components, systems or assemblies installed by Grand
Design RV. Grand Design RV is not responsible for the safety
or quality of design features, materials or workmanship of any
alterations by such suppliers.
Replacement Parts
Replacement warranty parts are distributed exclusively by au-
thorized Grand Design RV dealers or service centers. Grand
Design RV does not sell parts retail direct or to non-autho-
rized dealers. If an original part is no longer available, Grand
Design RV or your dealer will try to provide an appropriate
substitute.
Updating Your Contact Information
Federal record keeping laws require that we maintain a file of
owners of our RVs. Please help us keep your contact informa-
tion updated so that, in the event of a recall or customer notifi-
cation letter, you are notified. Please let us know (in writing) in
the event of a change of address or ownership, or if your RV
is stolen, totaled or destroyed.
