Thank you rhagfo and Craig..........I had a Pacbrake on a '97 Superduty 5 spd that towed a 4 car hauler, worked really good for me. Instaed of spending a ton of money for bigger axles and drum brakes I'll probably go with discs over the winter.
We don't have the new 5th yet but it looks like it will be a 331 RK Mountaineer, don't have a lot of steep hills out here in So. Utah but my biggest fear is running out of brakes....specially when some A/H pulls in front of you. Picking up a good used Trailer Saver TS3 also this week for $900...can't go wrong with that.......Dave
