Driving Impression

Driving the Dynaquest is enjoyable. I’m used to driving class A bus-style chassis in which the driver sits forward of the front axle. The extended hood and front axle of the Dynaquest made me feel I was driving a big SUV. The Cummins ISC engine effortlessly moves the coach through the gears, and I noticed it shifts at lower RPMs than other Super C coaches with a smaller ISB engine. The lower revs, plus the additional insulation Dynamax adds to their coaches, kept the engine noise down to a low, comfortable level. Coming from a rear-engine diesel pusher I expected the noise to be more like other front-engine motorhomes I’ve driven, but the Dynaquest was so quiet I was pleasantly surprised.

Handling is crisp and responsive but did not compromise the ride. Dynamax’s addition of massive 60mm Bilstein shocks absorbed every bump in the road, resulting in a smooth and comfortable ride. The Lexington seats are super comfortable and a cut above the brands usually found in motorhomes. The air-ride pedestals are a treat. Just sit down and press the lever to adjust the seat to your weight. When encountering a huge dip or bump, the seat removes the jolt by allowing the seat to move vertically like a big soft shock absorber. The comfortable cockpit seating, suspension, and visibility means you can drive this coach all day without tiring.

The shape of the cab resulted in reduced wind resistance, which lets the Dynaquest slip through the wind quietly and with ease. The cab overhead is aerodynamically clean and allows the air to gently glide over the top of the RV. The fuel fillers are hidden behind rotating fuel doors flush mounted into a contoured leading edge that blends the sidewalls into the cab. All of these aerodynamic improvements contribute to improved fuel economy. Although we didn’t have enough time to do an accurate assessment of fuel economy, other owners report an average of 10 to 12 miles per gallon.

Dynamax is uncompromising in their construction and design and sweats the details to provide the best possible product. If you are looking for a well-built and well-appointed motorhome with plenty of power and towing capacity, plus respectable fuel economy, the Dynaquest is worth a serious look.
