Jayco Seneca built on the M2 Freightliner Chassis. One of the most popular Super C' s on the market. The 2012 Jayco Seneca 36FK is an RV that is approximately 38 feet long. It has a 340HP Cummins diesel engine, a Freightliner chassis, and a 6KW Onan diesel generator. Other features include a power patio awning, slide-out room toppers, electric/gas water heater, 50Amp power cord reel, aluminum wheels, exterior entertainment system, automatic hydraulic leveling system, full color camera backup system, Xantrax inverter, cab over bunk, king sized bed, dual ducted roof A/Cs and 4 HD TVs1. The RV has an interior height of 84 inches. Everything was in working order when we stopped using it last fall. The Automatic leveler system does intermittently beep and flash when turning right or hitting a bump. Past that, everything seems to work as it should. CB antenna was unhooked when we bought it a year ago and never hooked up. We are down sizing and need a different floor plan. This coach drives amazingly well and averaged between 10-12 MPG on the road. Never gave any issues on the couple of trips we took, plenty of power and handled like a dream. You are welcome to have someone do an inspection before you buy it. It is available to look at during business hours at Freedom Auto Sales. We can also schedule a time outside of their business hours.
