Be aware that the effort to disconnect bars is the same as connecting them.
So.... raising the tongue will make it easier to disconnect.
And always make sure all parts of your body are not in the path of the cheater bar or anything used to connect disconnect. something goes wrong and you don't want to be in the way.
Also. If when disconnecting if the trailer/TV is not level but in a "V" at the tongue, the force on the bars increases. I doesn't take much of a "V" before the force on the bars can be extremely high if you aren't using the jack and you can be suprised/overcome by the force on the cheater bar.
When I put my trailer in the driveway I always disconnect the bars before backing in since there is a noticeable "V " at the tongue and I can tell you the force to disconnect w/o using the tongue jack is way higher than when level.
