I have a custom built open trailer with torsion drop axles. In my book there are lots of benefits. NO LINKAGE or Bushings to service EVER. Axles are dual 5200lbs with 15' wheels/radials with brakes at each end. Each wheel acts independently. Dropped the trailer as close to the ground as practical to reduce gate angle when loading/unloading mowers & equipment. Also no angle iron - all square tubing. I don't see any issues/cons. Save $ over the life of the trailer..

Unfortunately, you're gonna drag the rest of us in it too.
