Seneca by jayco

Not sure if this is the correct forum to ask this question so here goes.
I just saw a Seneca 37TS and I assume it is a class C.
It has a Cummings ISB 6.7L 340HP diesel on a Freightliner frame.
To me they look like a truck conversion and the wife fell in love with it.
I dont seem to find much info on these units can anyone help with more info on these units.
Thanks
6MM

I talked to a couple of owners.

Stiff ride, needing sway bars, and noisy engine on climbs were their major complaints. The liked the power, solid build, and the coach amenities. Dont know about mpg.

Here are is a thread I found:

Jayco builds the Seneca which is considered a Super 'C'. Not sure if they still do but they also built an Embark which was a Seneca on steroids. It was a Super 'C' that could tow a heavy trailer.
Older Seneca's were built on the GM chassis and were powered by the Duramax diesel. When GM stopped supplying the engine/chassis Jayco moved to Freightliner.

The Embark I believe is on an air suspension but not the Seneca.

Other builders:

Gulfstream builds the EndruaMax which competes with the Seneca and thr Super Nova which competes with the Embark.

HaulMark builds Super 'C' motorhomes that are really upscale and expensive to me anyway. Not sure what they compete against.

Major advantage of a Super 'C' is how much they can tow and carry.

As tuffr2 said, the Seneca is a Super C class. A Super C can go all the way up to a full class 8 truck chassis. But many are built on smaller class 6 or similar size chassis, like the Freightliner business class chassis or the Kodiak for examples. They are truck conversions in the sense they are based on a std truck chassis with the regular truck cab and front end, but with a motorhome from there back. Almost all Super C are diesel engines.

I have the Gulfstream Supernova, and yes it does ride like a truck. What do you expect? It *is* a truck. I wanted the heavier duty and ability to tow a car trailer without concerns. I do not think the ride is bad, just not exactly a luxury car ride either. Mine is built on an International 4200 chassis.

One of the bigger Super C is Renegade by Haulmark. Sometimes you will hear the term toterhome used. Look at Race, performance & street cars, engines, engine parts, trailers for sale and check the RV/motorhome section and you will see many of the larger truck based motorhomes.

I own a 2012 Seneca based on the Freightliner chassis. It is a beast. 9MPG uphill, downhill or towing my Chevy Tahoe. 2013/14 have airbags and air brakes and larger wheels. But my 2012 is still a really nice rig. 38 ft. 2 slides and 8K Onan. What else do you need?
