In response to the quality issue, I have a 2021 310 have had to replace electric over hydraulic brake actuator, replaced hydraulic ram for pushing out kitchen slide( nuts holding ram tight we’re just hand tightened), developed hydraulic leak. Kitchen island was found on floor the four screws holding the big cabinet to the base were sheared off , same trip the fascia molding on one slide was found on the floor when we stepped in so as far as quality built trailer I am Very disappointed
