Front-end shimmy comming down the mountain
New to fifth wheel hauling here and experiencing front end shimmy when braking at normal highway speeds (45-60mph) going downhill and hauling. I am hauling a 2013 Dutchman Voltage 3 axle with a 2013 C...

To the Op. I'd say you've got your answer.
Perhaps deglaze the rotors but otherwise it sounds like you just need to go slower on the hills. Get over in the right lane and start down the hill close to the speed you intend to descend at and let it speed up a little, then get the exhaust brake going to hold that speed. I'm guessing you're starting down too fast and then have to slow down via the brakes. Downshift if you need to hold it back more. Sometimes I'll end up going too slow (e.g. from the tunnel to Silverthorn) and will give it fuel to speed up some vs upshift to another gear that will run too fast. I suggest you err on the slow side especially when you're a new driver.
Watch the loaded trucks. Some of em just crawl down those slopes and they aren't touching their brakes. Then theres the fast ones who come down with brakes smoking. You don't wanna be them!
