Top models in Class C’s

[Mondooker]

There may not be a luxury Class C as such. But of all the manufacturers out there who makes multiple different models. What has been at the top of the quality models?

I don't know how much you want to spend, but Newmar makes a Super C now. There are others as well if you want something higher end.

All of them use the same components. Larger ones tend to be on Ford E-450 Chassis and there are a few using Chevy's.
Smaller units can be on Mercedes or Ford or Ram sprinter style vans.
As to house quality, again, they use mostly the same components. Generally most will tell you I believe that the Thor products tend to be the lowest quality, Highest quality is likely going to be like asking whats better, Ford or Chevy.
As a generality Coach House, Winnebago, Nexus, Entegra, Jayco, Coachmen, Gulfstream, Forest River all offer varying levels of amenities, and cross multiple price points. And yes the list above is somewhat close to a price breakdown with the first ones tending to a somewhat more expensive, and some would say , better lines.
If you are shopping new, warranty on the "house" could be considered by some as a telltale. Jayco and a couple others warrant for more than one year, Most tend to only cover for a single year.
