After a closer look, I noticed you said you actually ordered this one for $200:

I'm sure you haven't put a lot of street time on the truck yet, but I'm wondering if you feel that the extra proportioning valve added a lot of value for you? I may have found a similar setup (sans prop valve) for around $120. I'm torn about what sort of brake proportioning might be useful for me. My truck will either be used with nothing in the bed, or 6-8000 lbs in the bed. It's hard to imagine a setup that would be ideal in both scenarios. I'd lean toward having adequate rear brake pressure, but would likely risk skidding while the truck is empty.
