Workhorse Custom Chassis LLC will begin offering a 22,000-pound gvwr gas engine Class A motorhome chassis to RV industry OEMs beginning in August.

Currently, 18,000-pounds gvwr is Workhorse’s highest rated chassis.

The new gas chassis, code named W22, should become a viable alternative to the “entry-level” diesel engine chassis that have become popular with motorhome enthusiasts during the last few years, according to Workhorse President Tom Frey.

Although the price has not been set, Frey said the W22 would be priced below the comparable diesel Class A rails.

The key component of the W22 is the model year 2001 Vortec 8100 engine from GM Powertrain, Frey said. The 8.1-litre V8 has a 340-hp rating and 455 lb-ft of torque for improved towing, hill climbing and acceleration for passing.

“The Vortec 8100 is essentially a new engine,” according to a statement issued by GM Powertrain earlier this year. “Nearly 80% of its parts have been completely redesigned.”

Workhorse also has incorporated design elements to make the W22 “an entirely new chassis, not just an upgraded chassis,” Frey said.

The motorhome manufacturers that requested W22 prototypes are working with Workhorse on design refinements to optimize the attractiveness of the coaches they will build on the W22, Frey added.

The W22 will go into production early in August, said Andrew Taitz, chairman of Grand Vehicle Works LLC, the parent of Workhorse..
