This Seneca 2007, 33SS 4x4 Motorhome was built by Jayco on a 2006 model year Chevy C5500 Kodiak truck chassis. It's equipped with a very powerful & desirable 6.6 litre, LBZ-Duramax Diesel engine that was not required to have either the DEF or DPF emissions systems. ~ The Engine is completely stock and has always passed the very strict Arizona Emission Testing requirements with ease.

The Rear Axle is equipped with the Limited-Slip/Positraction upgrade, The Front Axle is equipped with manual Locking hubs.
We never abused this Motorhome over rough roads & terrain, but rest assured its 4-Wheel Drive system (and its additional ground clearance) will get you in, and back out of boondock camping locations far beyond the abilities of equivalent 2-wheel drive Motorhomes. It's very easy to drive, both around town and out on the Highway due to its Suspension & Steering upgrades. It'll easily cruise at 75mph out on the Highway all day long...

This Motorhome was factory equipped with a 1-piece Fiberglass Roof, and a 1-piece Fiberglass front Cap. I've resealed all of its roof-joints yearly with Dicor Self Leveling Lap Sealant every year and I've never found any signs of leakage. This Motorhome has been stored in my RV Garage whenever we weren't out camping, not left outside year around in the harsh Sun & Weather...This Motorhome has a Residential-sized Queen Bed in the bedroom. Its dinette converts into a secondary bed & its recliners can serve as very comfortable sleeping for 2 more.
This Jayco Seneca 33SS was the shortest (33'-6) & lightest weight of all of the other various Seneca models. It was only produced for 1 year, so it's an extremely rare and difficult to find Motorhome.Here's a link to the 2007 Jayco Seneca Brochure with lots more info about the amazing features of this 33SS motorhome: https://library.rvusa.com/brochure/2007_Seneca.pdf
Only known issues are purely cosmetic, including the flaking clear coat on front cap, various small paint chips & a small paint damaged spot located near the left-rear corner. (shown in my pics)
This Motorhome is located in Surprise Arizona, 20-miles west of Phoenix.
We'd planned on keeping this amazing Motorhome forever, but now selling due to ongoing health issues.
