I purchased my Grand Design Reflection in 2014. As far as I'm concerned, they have good quality. But their best feature is their customer service. If you ever have a problem, you can call their customer service line and talk to a real person who can usually handle your call or question in just one try.
As for the lack of shock absorbers? These units come with the Equa-Flex system which really reduces vibration and road induced damage. I have over 20,000 miles on mine now, and there is no issue with vibration or shock induced problems.
