I just had a Jake brake installed on my truck today. So far I am impressed with how it works. I will give it the true test this weekend when I head out camping with my fiver. Does anybody know off hand how the brake effects fuel economy? I think I saw in one of the other forums that MoparMan has one.

I just got back from my 4 day camping trip. It was a little over 500 miles. The brake worked great and I average 13.3 mpg over all. I'm satisfied with that. :thumbsup
