Jayco Seneca 37K Super C exterior

Along with other changes to its five-model Seneca — including a new 37K floorplan – Jayco Inc. has upgraded the entire Super C line with the new S2RV chassis from South Carolina-based Freightliner Custom Chassis Corp. (FCCC).

The S2RV front-engine diesel cab chassis is designed and built specifically for the RV market, and caters to drivers who want the power and performance of a diesel without the cockpit of a conventional Class A. 

Jayco MotorHome Group Regional Sales Manager Ryan Eash said the S2RV chassis has a number of improvements over the previously used M2 chassis, also from Freightliner.

“You get a 360 horsepower Cummins engine instead of the 340. You get the 3000MH six-speed Allison transmission instead of the 2500,” he said. Other improvements include 100 gallons of diesel instead of 74, more Diesel Exhaust Fluid (DEF) capacity and pass-through storage.

The Seneca 37K model, with an MSRP of $244,900, features a 1 1/2 bath  layout with a spacious rear bath and a half-bath tucked in behind the living area’s angled entertainment center, which is opposite an L-shaped sofa for optimal TV viewing. The sofa and a dinette are housed in a full-wall slide on the driver’s side, while the curb-side slide holds the bed in the master bedroom.
