iN•Command® with Global Connect®

MONITOR AND MANAGE YOUR RV FROM YOUR SMARTPHONE

In 2015, Keystone engineers teamed up with ASA Electronics, a leading electronics firm, to create the RV industry's first reliable app-based control system—called iN-Command.® iN-Command successfully eliminated the clutter of switches and buttons replacing them with a clean, easy to use touchpad along with an app that transformed smart phones into a multi-functional remote control. Fast-forward to 2018 and the breakthrough iN-Command system is changing the game once again by incorporating “Global Connect” into the latest generation of iN-Command. This new, smart-home system makes it easy for Keystone owners to control and monitor many of their RV’s functions from anywhere in the world using Wi-Fi and cellular data connections. 

HOW IT WORKS

The brains of the system is the Body Control Module (BMC). Commonly located in the pass-through of your Keystone RV, the BMC houses numbered, color-coded wiring and a series of solid-state relays. These relays switch on and off the various electrical components of the RV.

Communicating with the BMC is the Display Commander— a state-of-the-art, wall-mounted touchscreen that can be personalized to your preferences.  Touching a function on the Display Commander sends a signal to the BMC to open or close a circuit.

Virtually all the Display Commander functions can be duplicated on your smart phone or tablet through the iN-Command app (download from the App store or Google Play).

Here’s the kicker: Using Wi-Fi and cellular data connections, in-Command with Global Connect gives you the ability to monitor and control many vital functions of your Keystone RV from anywhere in the world. 

SEAMLESS INTEGRATION WITH GMC AND CHEVROLET'S ON-BOARD SYSTEMS

For Keystone RV owners with compatible systems, this means you will not only have the convenience of iN·Command on your smartphone, but you will soon be able to monitor and control your rig’s controls from the dash of your truck.

The new implementation of iN·Command offers an additional and phone-free way to access to tank and battery levels, lights, water, HVAC, generator functions and more while on the road–the system also sends alerts should there be any RV system errors or components that need attention. Off the road, RV functions can be accessed anywhere in the world with a Wi-Fi enabled smartphone from the myChevrolet or the myGMC app.

Innovation Leadership

These models feature exclusive ground-breaking components and technologies from the Keystone Inovation Lab.

MaxTurn™ Technology

MAX TURN™ MAKES TURNING AND MANEUVERING A BREEZE

Keystone fifth wheel RV owners can make tight turns more confidently with Keystone's EXCLUSIVE MaxTurn™ Technology. Developed by the Keystone Innovation Lab, MaxTurn's patented tube frame design combined with a tapered fiberglass front cap provides and additional 8" of turning radius than the standard straight tube design. MaxTurn delivers an expected turning radius of more than 95° without an expensive and difficult to maintain swivel hitch pin.

Key features include:

• Single-piece bent tube replaces a welded three-piece frame
• Eliminates need for swivel hitch pin and the maintenance that comes with it
• 8" more turning radius, more than 95°
• Greater manueverability and safety
• Protects tow vehicle from damage

*Not available on Raptor, Carbon, Fuzion, Fuzion Impact toy haulers or Springdale and Hideout fifth wheels.

12V Color-Coded Wiring Standard

SMART & SIMPLE

Learn how Keystone’s EXCLUSIVE color-coded 12V wiring is different from conventional RV wiring and why it’s a better for both owners and service technicians.

• Easy-to-trace circuits help dealer service techs troubleshoot and complete repairs more quickly, saving owner’s time and money.
• Clearly labeled wiring helps savvy owners with DIY diagnosis and repair of technical issues.

KeyTV™ Multi-source Signal Controller

Plug-and-play receiver seamlessly manages broadcast, satellite, and cable

Ask any camper, trying to get the television to work in an RV has been famously difficult. So in 2019, the Keystone Innovation Lab partnered with some of our suppliers to figure out a better way for Keystone owners to both connect to entertainment options and make that connection more reliable. Enter KeyTV™, Keystone RV's EXCLUSIVE multi-source signal controller takes the guesswork out of RV television operation and improves the signal quality at each television in your coach.

• Cable, satellite, and over-the-air connections go through a single access point, the KeyTV™ controller, typically located in or by an exterior storage compartment.
• A "home-run" line from the controller connects the entertainment feed directly to each television in the RV. This eliminates 50% of unnecessary cable, splitters, jumpers, and multiple connections which degrade signal quality and result in poor picture and audio quality.
• The antenna booster is located in the KeyTV controller so owners always know where it is and don't have to guess.
• Auto-sensing technology eliminates frustrating A/B switches. KeyTV knows when the camper is hooked up to cable and automatically switches the feed from the over-the-air signal to cable.
• Requires no additional wiring for satellite hookup and is compatible with most DISH®, DirecTV®, Shaw, and Bell products.
• Allows owners to connect a satellite receiver on any television in the coach.
• Color-coded wiring makes it clear which connection point feeds which monitor.

Blade™ High Performance Air Flow System

Delivers 20% More Air Flow

Today’s high-performance air conditioners are only as good as the systems that deliver the cooled air to your coach. Keystone’s new, patented Blade™ air handling system completely re-engineers RV ductwork and vent systems to deliver an average of 20% more cooling power*. Blade is also built to withstand the rigors of the road with rugged components designed to eliminate inefficiencies that commonly develop in RV HVAC systems over time.

New duct elbows and wyes

Redesigned to maxmize A/C output

Brilliantly designed to accelerate airflow with duct elbows and wyes that feature enlarged inlets and narrow as they push cooled air from the air conditioner through the full length of the ducting. This design reduces air turbulence (and the noise that goes with it) and increases air flow to more effectively cool the entire coach.

Injection-molded connectors

Eliminates foil seals

Inspired by Keystone’s Tuf-Lok™ duct connector design, the Blade™ system completely eliminates ALL failure-prone foil tape seals with the addition of new injection-molded duct inlet connectors and end-run caps, a new vent diffuser featuring a “collar” connector, and a redesigned A/C plenum box constructed from foil-faced foam board wrap. With these components, Blade addresses each common failure point: smoothing air flow, reducing leaks, and minimizing cooling performance loss over time.

Blade™ signature vent collar and diffuser

Delivers faster, whole coach cooling

The Blade™ signature vent collar and diffuser creates convection air currents within the coach, delivers 360° cool air circulation, and eliminates hot and cool spots. The new Blade vent also gives owners the ability to adjust air flow if they choose.

Tru-Fit™ Slide Construction 

A BETTER FOUNDATION

A long-time RV owner recently stood in our office and pronounced that auto-leveling and slide rooms were the industry's two greatest inventions, and we have to agree. As great as slide rooms are, it's important to remember that they aren't all created equal.

When shopping for a new RV, look for slides that are well-engineered and well-built to both keep water out and stand up to the mechanical stresses of moving hundreds of pounds in and out of your coach.

The Innovation Lab's Tru-Fit™ Slide contruction tackles durability and weather protection head on.

With custom-engineered frames for every floorplan, Keystone RV eliminates the compromises other manufacturers are forced to make as they try to adapt new floorplan designs to work with stock frames. Keystone's Tru-Fit frame design optimizes each slide's position to reduce stress on the structure and motor, resulting in a more durable build and consistent performance. A flexible rubber seal is added to both the slide-out structure and the side wall, doubling the RV's protection against the elements.

The result? More durable and weather-resistant slide rooms that are most definitely built for the long haul.
