Yes we have a 2012 with a maybe 50 thousand km on it. I haul a Goldwing in it .As you can see frame has cracked up on both sides, axle frame was all twisted . Fault was frame gauge to light for trailer , steel made of pig steel ,also no reinforcement on I frame.
I ended up putting 2x6x1/8 steel channel front to back , new axle frame 5" so side of tires will not rub frame as kept blowing tires . Put 5,200 lb axles in.
Factory axles had not been lined up and trailer was dog tracking,with new axles in iam getting 6L per 100 km better. The original 3,500 axles were to light causing axles to bow replaced with 4,400lb of which brakes parts not available any longer , so went with 5,200 lb .
Now trailer pulls much easier, no sway tires not rubbing on frame. And with Road Armor tandem Equalizer also installed there is less neck pain while towing. Also supports put across on each shackle mounts.
Yes lots of work went into rebuilding this trailer in 2019 otherwise it was scrap, driving home with frame cracked up was most scarey 800km ever. If I would have made a sharp turn or swing axles would have came out. Prayer got us home!
Forest River didn't help at all, they blamed Lipport whole frames who in turn blamed Foerst River as engineers gave specs.
Now we feel safe on road around you and your families . Please check your frames for cracks! Don't let me see you in obituaries or others from trailer axles blowing out with trailer and truck going to the wreckers.
