We have the 22K F53 chassis. We have tow-haul mode and use it a lot. It is very helpful going down grades (and up for that matter). Of course, we have spent the last five months mostly in the mountains. On really steep grades (8-12%) we still have to brake but not nearly as much as if we didn't have it. It does a decent job of keeping speed under control.
