Damn, your bus needs a Jake brake, then you'll really wake up the neighbours. When Al had his old #13 there's a short YT clip of it using the Jake in Phelan, and it sounds great!
And to think my school district went out of their way to buy these buses, just because they were so popular with the drivers. We must have had dozens of these, my middle school alone needed ~8 buses to get the kids home every single day, and about half of the middle schools were bussing kids around.
