TrailAire has a prototype being tested that takes care of the chucking or porpoising AND the bounce. Rumor has it that it may be available by the end of the year, but cha know about rumors! They also have a new equalizer arrangement, not the center point, this one is called Equa-Flex (or something akin, hey, it is the middle of the night --
) Their web site, does not have either of these, but they are installing the Equa-Flex right now. EF is several hundred dollars less than their center-point suspension.
