I don't put much stock into the list. The bigger the company the more complaints your going to get. We had a 2017 Forest River Wildcat that had some cosmetic issues in the exterior fiberglass and a floor that developed soft spots. Forest River (at least the Wildcat division) replaced our fifth wheel without me even asking. While it sucked having to have repairs, I was blown away that they would do this. They also would compensated me for any mods that couldn't easily be taken off (such as a pressure tank and new bath fan), plus as a bonus the new one came with a second AC unit and 16" tires vs the 15"
Forest river builds **** like the rest of them but I cannot complain about their service. When reading about the horror stories of getting repairs done I didn't have high hopes but they proved me wrong. It also helps having good dealer to go to bat for you as well.
