Hey Crabman, mine the motor sits in the middle with a shaft coming off each side that runs out about 3ft to the drive gears. Mine also is a shallow slide that only goes out about 16in too, might have more weight that a dinnette an couch, as in mine its the couch an kitchen.. I'm going to try to get a video of it going in an out just so everyone can see how much this thing moves..
