This may not be all that helpful, but we have one season on a new Sunseeker 2430S with the Slim Rack system, and have no complaints at this point. We have always been very careful to have the rig leveled with the BigFoot levellers, and make sure not to load any heavy items in the slide, and always ensure a clear path for the slide to avoid any binding. We also take the time to lube the seals and the gear tracks on a regular basis.
