BHarrison - The best brake controller I've ever used is the Ultima 2020 by <A target="_blank" HREF=http://www.jordanbrake.com/>Jordan Research</A>. They're unique in that there's a cable that runs from the controller to your brake cable. That makes them a little more trouble to install, but once installed, they work great. Since they "know" exactly how much pressure you're putting on the brake pedal, you can set them to lead your truck brakes a bit, which really helps you in sudden stops. What you end up with is fully proportional braking that always brakes exactly the amount you want it to, because you're controlling it with your foot pedal. It's the most natural and easiest system to use, because it works exactly the same whether you're towing or not. Also, there's never any "ramp up" delay, so in a panic situation you get immediate braking to the trailer leading the braking to the truck, so you don't have to wait for the trailer brakes to catch up, nor do you run the risk of jack-knifing. Check out the message board on their site, if you want some opinions besides mine. Many of the posters there have owned almost every controller on the market and settled on the Ultima. They're more expensive at $140, but I think they're definitely worth it - especially if you think you ever might need to stop in an emergency situation. /w3tcompact/icons/smile.gif Also, they've got guts - one of the trailers I use mine on has 3 9,000 pound axles, all with brakes. Under full braking with a heavy load, they draw well over 20-amps, and the Ultima handles them easily.
