the rear engine mount is supposed to dampen your engines tendency to want to twist. If the rear mount is looser it reduces vibration and allows the engine and all connected components, transmission more freedom to move around. this sometimes results in less than stellar take offs from a standing start (wheel hop) and a rough time downshifting (when engine breaking). A stiffer rear engine mount eliminates a lot of the twisting motion, reducing wheel hop and such, but also tends to transfer more engine vibration into the rest of the car. for some people the crispness of the ride is worth the extra vibration. So in essence the RMM will add more vibration in the cab since it isn't being transferred through the rest of the drive line like the stock mount would
