FYI - found our 2018 Miramar 35.3 bed frame is literally falling apart (see pictures). Part of frame found laying on the RV's floor as well as decorative trim pieces. Failure apparently due to poor welds. Also bed rollers are pulling away from support frame. Thank God we had a local dealer who was able to install some 'temporary fixes' until we get a permanent solution via the manufacturer (will post fix pictures in another post). Hah to that thought.
