2005 PEAK CHASSIS Series

Manufactured exclusively for

“A HIGH PERFORMANCE CHASSIS THAT YOU CAN BELIEVE IN.”

MISSION: Peak Chassis was begun when Western RV entered the diesel-pusher, Class A motorcoach market. Our sole purpose is to design and manufacture a state-of-the-art, custom-builtmotor coach chassis for the Alpine Coach product line. Our goals are simple: Build a chassisthat is rugged and reliable, make it highly serviceable, and have it deliver uncompromisingroad handling characteristics.

RUGGED FRAME: The Peak Chassis engineers could have built any type of frame theywanted to in order to support the Alpine Coach. They could have chosen to build a totallywelded structure such as a semi-monocoque or full-monocoque frame. Instead, they chose tobuild their frame like Kenworth®, Mack®, Peterbilt®, or Volvo® truck companies do. Whyyou ask? Because of one reason, STRENGTH.

Any knowledgeable chassis engineer knows that nothing beats the strength and durability ofa rail type constructed chassis. As a customer, you have to ask the question, “If monocoquechassis are so strong, why don't over the road trucks use them?” When shopping for a motorcoach, consider the chassis frame as the foundation of your mobile home. It needs to be asstrong as it can possibly be. After all, it supports thousands of pounds placed upon it by thebody, and the water, fuel and propane.

Our frame is rugged, Huck®-Bolted together like a freight train. All brackets, bulkheads,outriggers, steps, wheel wells, and room slides are blueprinted, laser cut from solid steel, andintegrated into the frame at our factory; there are no welded on afterthoughts. All ourcomponents are attached to the frame using the toughest fasteners in the business – Grade 8bolts and lock nuts that are zinc plated and yellow dichromate finished to prevent prematurerusting. The frame is finished off by being descaled, degreased, and etched with anautomotive type soda blast. From the frame preparation booth it gets a primer and overcoatof some of the toughest polyurethane paint in the business. Then to top it off, a toughundercoat is applied to all 4 wheel wells. Take a walk around our chassis frame; it boaststwo things, brute strength and quality!

RELIABLE COMPONENTS: When we went shopping for the components, we wanted thesame thing our customers wanted, the best that money could buy. Therefore it made sense touse the toughest, most reliable, serviceable name-brand components we could get our handson. We wanted you to say one thing when comparing our chassis with all the others, “Wow,these guys are serious about keeping me on the road instead of in the garage.”

SERVICEABLE: Everyone has expressed at one time or another, “Why did they have to putthat part where I can't reach it to fix it?” Well, we listened hard to our customers and dealerson this subject, and we made room, lots of room, to tinker on your engine, hydraulic jacks,generator, batteries, etc. No scraped knuckles here!

We even came up with an illuminated service center which includes such conveniences asengine and transmission oil dipsticks, a diagnostic plug for troubleshooting your electronicengine, an auxiliary air connector to fill your tires or power air tools. In your service centeryou also have unobstructed access to your air filter and it can be changed out in minutes.About time, right?

We thought a lot about the little details that make a big difference between enjoying yourPeak Chassis or just plain parking it. Little details such as painting our chassis frame a

reflective gray color instead of black in order to see and trouble shoot leaks faster. Detailssuch as labeling all our hoses, electrical cables, and harnesses for faster part response fromthe factory or dealer; or using hub piloted rims like you have on your car so a mechanic canchange your wheels and brakes faster than he could with a stud piloted rim.

SERVICEABLE (Continued):

Details such as an aluminum radiator so it can be fixed anywhere in the U.S. instead ofthrowing out a plastic one. Call us old-fashioned but we want to say one thing aboutservicing the chassis, “If it is easier and faster to work on, the better for our dealers andcustomers.”

ROAD MANNERS: Virtually everyone in the automotive business understands that the key to agreat handling vehicle is proper weight distribution. While most coach manufactures arestruggling with this issue, we worked hard and got it right the first time. What we came upwith is a nearly 60% rear and 40% front weight distribution. What this means to the driverand it's occupants is that this coach is as safe as it is fun to drive. It means the componentswork properly and harmoniously together. It means less driving fatigue to the driver becausehe is in control, not the coach. Proper weight distribution is everything in regards to how acoach handles and feels when driving down the road. The Alpine Coach, with its customPeak Chassis underneath, assures one thing to our customers: you invested in a great drivingcoach that rides like a sports car!

SAFETY: Give them a brake! The Alpine Coach was the first motor coach in the industry tooffer and certify hydraulic all-wheel antilock disc brakes. Big deal, right? Read on. Whyhydraulic disc brakes instead of traditional air drum style brakes? The answer is simple.Less brake fade and better brake pedal feel. Most truck and motor coach people know thatbrake shoes located inside brake drums fade due to excessive heat and brake dust buildupwithin brake drums. With hydraulic calipers and rotors, the brake lining heat is dissipatedthrough cooling fins that are exposed to the outside air temperature, the heat is not held in bythe brake drum! Please consult your dealer or WRV for performance comparisons.

PERFORMANCE: When you marry the highest quality components with an excellent roadhandling chassis and couple it with the industries best performing powertrain packageavailable, you have a vehicle that will flatten the toughest of mountain grades and keep youout of trouble. Period!

CLOSING STATEMENT: At Peak Chassis, as with the rest of the family of recreationalvehicles produced by Western RV, we can honestly say we are passionate about what we do.We want to make owning a recreational vehicle built by our family your best experience everfor your family.
