We have a 2021 3121RL and have developed a small crack protruding out from the lower left corner of the bedroom slide most likely due to the dreaded frame flex issue. We are located in western PA just north of Pittsburgh. I know all about Affinity RV and can take the rig to them. Keystone, though, has provided the name of Colton RV near Buffalo, NY as a place that does this sort of repair work. They are 3 hours away verses 6 hours to Affinity. Was wondering if anyone is familiar with Colton RV and had the frame flex repair work done by them? If so, would you recommend them? TIA!
