If I had to go down a hill real slow so be it.
This is true if you are going slow enough, then yes, just being in that low of a gear will give you drive axle braking with compression. But if you are traveling down a slick hill at a safe speed, say 30 mph and need to slow or stop because of an obstruction, you need to use the jake because the trailer will lock before any air is applied to the drivers. You will need all tires on the ground in braking mode to slow or stop. Of course you take into consideration how steep it is, how icy, what gear you are in and what rpm you are at and if you are running chains.
I was talking about big trucks but small ones are simular.
