I have a 2004 4-Runner and I tow it behind a motorhome with the front wheels on a tow dolly. I currently disconnect the rear driveshaft each time I tow manually which is a real pain. I have been looking at drive shaft disconnect units but I am unsure whether the really work as advertised. Does anyone have any experience or first-hand knowledge about these units? I will probably keep my existing driveshaft for real torque-intensive situations but for day-to-day cruising around it would be nice just to pull the lever and go. Thanks!
