Fontaine Modification Medium & Heavy Truck Operations has introduced its Kenworth Premium Sit-Down Dual Drive modification — a sit-down dual drive (SDDD) conversion for Kenworth T180, T280, T380 and T480 medium-duty conventional trucks. Fontaine also offers a sit-down dual drive modification for the Kenworth K370 COE model.

SDDD modifications add a right-hand drive station to the vehicle, enabling drivers to comfortably operate from either the right or left side. The company says that this is crucial for applications where the driver needs to operate curbside, like refuse collection, street sweeping and road striping.

Fontaine’s new Kenworth Premium Sit-Down Dual Drive modification is designed to make the right-hand driving position virtually identical to the original left-side position so drivers can operate with equal comfort and efficiency no matter where they are sitting. Fontaine’s team performs the conversion at its Chillicothe, Ohio, modification center.
