I'd say in the price range they are no worse than any of the other companies. Jayco offers a good bit for the money and they have a 2 year warranty. No one else really offers a 2 year warranty in that price range nor just above it except KZ which if i remember correctly is also 2 years limited and also owned by Thor.
You're buying an RV, nothing is going to be perfect. The stupid thing drives down the road at 60+mph. Stuff is going to break and or not work, most of it will be parts that the manufacturer doesn't even have control over.
If you're in that market segment, Jayco is a good buy. You can also look at Grand Design who makes a good unit for the money and has a bunch of different trim lines.
Compare and contrast construction methods, options and price then go from there.
