You could use a driveline brake for the parking brake. I've used them in the past. The nice thing is you have the advantage of the gears working for you as well.
The SD stuff is pretty nice, but even those parking brakes are pretty little. They are great if you are just parking the truck, but with a good trailer it's everything those SD parking brakes can do.
