Yeah, you can't use a Jake or exhaust brake in town... BUT you can scream around all hours of the night in a little super tuner all you want.
I was driving this old Gmc tree truck, it was fully loaded towing a chipper, it was old, no power brakes, steering. Saw a cop had someone pulled over in the right lane so I slowed down and got into the left. With no signal or warning the cops pulls out into my lane and scares the Hell out of me. We ended up having an argument on the road. He was hollering at me, I was hollering at him, the crew couldn't beleive it, they were just trying not to get deported. In the end he won, of course, but he knew how close he came to being roadkill. In retrospect I guess I should have just flattened him. It was on a steep hill coming out of Chestnut Hill, in fact it was Chestnut Hill. Yeah, i am always careful with a load on, never skimp on the brake work. I had my F350 inspected, they put badges on it, in my mind I was thinking " Man, didn't they see that rusty brake line"? It blew out after I stacked them 2 chords on. Good thing it happened in my yard.
Rick has this humongous container truck, man, its something to see go bobbin down the road. This thing is huge and heavy, I think its a 60 yard container. These are all small, windey,hilly country roads around here.
