Detroit Chassis LLC is shipping 2004 Ford F-Series Super Duty gas-engine Class A motorhome chassis with improved ride and handling.
Detroit Chassis, a unit of Spectra LMP LLC, has assembled Class A motorhome chassis using Ford components and marketed under the Ford brand name since 1999. Detroit Chassis, owned by Michael and Carlton Guthrie, also has worked with Altair Engineering of Lansing, Mich., since 1999 to design Class A motorhome chassis.
When designing the 2004 Ford F-Series Class A chassis, Altair used “a variety of engineering simulation technologies to address the suspension and steering characteristics for improved ride and handling,” according to the company.
Altair also followed a “low-cost/low-volume strategy” requiring “efficient project management, utilization of the latest engineering tools and efficient communication with parts suppliers.”
According to MotorHome magazine, a sister publication of RV Business and RVBUSINESS.COM, the Altair design team did the following to improve ride and handling for the 2004 Ford F-Series:
• Used full channel frame rails to the end of the frame on all chassis.
• Increased the top-of-frame to ground height by 2.6 inches for the full length.
• Mounted the fuel tank 2.6 inches lower between the frame rail for improved fuel-fill without a loss of ground clearance.
• Included a heavy-duty track bar front suspension with the 22,000-pound GVWR model. (It’s optional on the 15,700-, 18,000- and 20,000-pound GVWR models.)
• Used Michelin 235/80R22.5 G XRV tires with 22.5-inch wheels.
