This has been an incredible RV. The perfect amount of power and size to get you into the smallest federal and state RV parks, yet long enough for complete luxury. This has been very gently used and very well taken care of. It has the upgraded Cummins 360 HP, which also added 150 ft-lbs of torque. This is a Cummins option, that is a factory upgrade, which includes a new data plate from Cummins. We pulled a boat, a trailer and a car, and never would even feel them behind you. https://www.jayco.com/tools/archive/2015-seneca/standards-and-options/ Freightliner Business Class M2 chassis.
