Same idea as a torsion axle, the rubber bumper is taking the road shock out of suspension.
There are also short bolt on versions of the torsion axle avaiable.

When I picked up my new axles from the srping shop, there right in front of me is a display for the full length torsion axles. Man I wish I had of seen that before I ordered my new axles.
They sure do make for a nice towing trailer. Our old Airstream didn't telegraph the ride back into the truck like the leaf springs on this Dutchmen.
If you are considering going there, make sure that the swing arm is adjustable and will give you enough clearance in the wheel wells. You have to be able to get the stub axle to provide the same clearance as the straight axle does.
If you go with the Timbren kit, you will want to have it installed at a shop that can laser align the axles as they are mounted, to get the wheels running true.
I definately concur with Aaron, there are way more pluses than negatives with that type of axle. The biggest is independent suspension on the trailersand stuff dosen't bounce around in side the trailer as much as the straight axle.
