Excellent. Do you have to mess with the diesel particulate additive stuff on it? I know our '06 was about the last year before the exhaust rules changed, and I'm thankful the engine was capable of handling low sulfur and didn't need the emissions mods. The C9 is a great engine; yours probably is one that is actually tested out at 425HP - Dave A. would know. At that length you might have to watch your carrying capacity, but it sounds like the coach is pretty capable as loaded. So you went from a compression brake to an exhaust brake, or did they put a Jake on that long chassis-ed C9?
Good luck finding the ice dispenser... out of curiosity because we have the same fridge (ice only, no water), I spent some time searching for one in case ours ever broke like the one in our GE here at home did. The icemaker is everywhere, a Frigidaire built unit I think. But the dispenser/bin seems specific to the 1402. I've admired our 1402 for its ability, lack of problems, capacity, and features over other models I've had and seen, and there's none of the issues that so many have with Norcolds in recent years. My only disappointment is they quit making it for some reason, so an essential part like this is apparently so suddenly rare. I'm hoping that fellow I posted a link to can offer some guidance for you.
