Phil,
Isolator is a Pin replacement. Trailaire and others, (5th Airborn? is that one?)are also pin replacements.
They have air bags and shock absorbers to CUSH the ride.
There are also hitches that have air (sorry, this early in the AM, the names escape me). Have said a number of times, if we knew when we purchased our first hitch we would have had an air type hitch. More $$ up front, but we feel it would have been WORTH IT!!!
The GlideRide and the MorRyde pin box replacements are great for chucking or porpoising, as Mike points out, they really do the stuff, everyone that has them loves them.
Al and I prefer the air bag type pins, we are most concerned about reducing stresses on the frame. It is our opinion, from watching the action of the 5er, the Isolator and the truck while going down the hard road that the Isolator is helping to protect our frame and our rig. The ride in the truck is better as well.
Good luck finding that electric bug.
