if you are using a slraight load 2 horse trailer and only hauling one horse you haul them on the left (drivers) side. this is said to prevent tipping.
Overdrive is the normally allowed position ( it won't shift into overdrive until the speed is fast enough )
Overdrive should be used when you're pulling a trailer or extra weight in the bed. At a lower RPM there is more torque, therefore more pulling power.
Overdrive is the normally allowed position , but it won't shift into overdrive until the speed is faster such as on the highway / freeway

Yes, under most conditions you can use overdrive. If you are pulling a heavy trailer, or the vehicle is heavily loaded, I would recommend you don't. If at anytime you a driving loaded and the transmission starts changing gears constantly, you should disengage the overdrive.
Overdrive is the normally allowed position so you don't see the light on If you turn OFF the overdrive , the overdrive off light will light up or if there is a problem the overdrive off light will flash
