Landmark 365 User Guide
This guide is intended to assist Heartland Landmark 365 owners by augmenting the information
found in the Heartland Landmark Manual.
Note that as model years change, Heartland introduces changes to the product. Changes may also
be made mid-year. As a result, it’s impossible to stay up-to-date for very long in a document like
this. Nevertheless, the information here may prove helpful to you. Check the date of the
document in the footnote. If the document is more than 1 year old, some information may be
dated.

Landmark 365 User Guide
Landmark Evolution to the Landmark Three Sixty Five
Heartland RV’s first product was the 2005 model year Landmark, released in mid-2004. Since
then, Landmark has gone through many changes. In mid-2014, Heartland re-launched the
Landmark as the Landmark 365 product. Landmark 365 was designed with the full-timer and
any-timer RVer in mind.
While some aspects of this guide would apply to all Landmarks, many items covered are
Landmark 365 specific.
Introduction to Landmark 365 Features
There’s a lot to cover in a Landmark 365, but the Control Panel is central to using the coach. Let’s start
there.
Control Panel
Most controls for the Landmark 365 are grouped together and are labeled clearly. Additional
explanation follows on several controls.

Landmark 365 User Guide V1.1.pdf P a g e | 8Version 1.1, March 10, 2016
Slide Operation
Landmarks have individual controls allowing you to operate each slide independently of the others. This
allows you to open and close the slides in the sequence that best fits your needs. For example, at
roadside rest stops, it’s possible to extend the kitchen slide by itself to prepare lunch or grab a snack.
Note that it’s a good idea to let go of the rocker switch as soon as the slide reaches full extension or
retraction. If you don’t, the pump will continue to run under a higher than normal load.
Exterior Lights
Flood / Scare Lights / Porch Light / Entry Light
Flood lights, sometimes known as “scare” lights, are mounted near the roof on each side. On the right-
hand side of the panel there are individual rocker switches for the light on each side. There’s also a
switch for the porch light located over the outside steps, and for the entry light, located in the ceiling,
just as you walk into the coach. The entry light is also used by the “Welcome Back Feature” which is
explained more fully later in this document.
Step Light
There is a light located below the entry door, behind the steps, to help illuminate the steps at night. The
switch is located in the control panel, but is not typically marked. Location of the switch in the control
panel area will vary depending on floor plan.

Interior Lights
The “lounge”, “kitchen” and “ceiling” ceiling lights on the Landmark use extremely low power/low heat
LED fixtures. This reduces power consumption when running on battery power and reduces heat load
when running the air conditioning. Each has its own rocker switch along the bottom row of switches on
the control panel.
Night Lights
To help find your way to the bathroom or kitchen at night, several floor-level night lights can be turned
on with a single switch. There’s a switch at the entrance to the bedroom, and another near the stairs.
The two switches operate in a 3-way configuration where either switch will operate all the lights.
Welcome Back Light
When you open the main entrance door, a switch under the door frame activates the Welcome Back
Light feature, turning on the ceiling entry light over the doorway. This allows you to enter the coach,
and turn on other lights without fumbling in the dark. The light goes out automatically after a pre-
programmed interval. The Welcome Back Feature is disabled when the Entry Light switch is turned ON.

Tank Gauges
Pressing a small button under each indicator lights up the display to show the water level in each
holding tank and the approximate voltage level of the 12V DC power system. The Gauges give a very
rough indication and can be affected by how level the coach sits, and other factors.
Water Heater Electric
The dual-mode water heater can be operated in electric-only mode, LP mode, or both at the same time.
