Blade Pure™ Airflow System

20% MORE COOLING POWER + AIR FILTRATION AND SOUND DAMPENING

A thoughtful combination of new-age efficiency and residential comfort, Blade Pure takes camping comfort to the next level. Now available on Alpine, Avalanche, Arcadia, Cougar, Montana, Montana High Country, & Sprinter.

MERV 9 Filtration

Tested to remove up to 50% of 1-3 micron particles for cleaner, healthier air. Blade Pure removes contaminants such as dust, mites, pet dander, pollen, mold, and auto fumes providing an extra layer of safety and peace of mind.  According to the EPA, indoor air can contain 2-5 times the amount of pollutants found outdoors, Blade Pure ensures those suffering from asthma and allergies get to breathe easier while traveling the country or weekending at their local campground (Indoor Air Quality, 2018).

The Quiet Series

The Coleman-Mach Q Series is undoubtedly the quietest air conditioner in the industry. With a combined noise reduction of more than 10-15 decibels over traditional A/C's without filtration, campers will enjoy movie nights, conversations, and better sleep without the distraction of a loud air conditioning unit.

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.

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.

4G LTE and WiFi Prep

Keystone RV Company now offers 4G LTE and WiFi prep on every model we manufacture. Our engineering and sourcing teams have developed a solution that makes it simple, easy and affordable for owners to add WiFi or cellular connectivity to your coach.

Winegard AIR 360+ Omni-Directional Rooftop Antenna
Eliminates dead spots

Every Keystone RV includes the Air 360+ antenna with wiring connecting it to a receiver plate for easy intallation of a WiFi router. This antenna receives AM, FM and over-the-air television signals, and is HDTV compatible. It also features dual 4G antennae to optimize reception, two times the signal strength, and a built-in gain low noise amplifier to minimize interference.

Winegard Gateway 4G LTE WiFi Router
Prepped and ready for installation

Stay connected while parked or while traveling. Your system is designed to work with the Winegard Gateway 4G LTE WiFi Router (GW-1000, MSRP $299). This router clicks seemlessly into place on the pre-installed wall plate and activates the 4G LTE antennae in the Air 360+. The Winegard Gateway supports HD streaming with 150 Mbps max and 4G LTE download, amplifies park WiFi, distributes you WiFi signal for up to a half mile, and offers WPA, WPA2 and WPA mixed wireless security.
