As others have said. Gear down. Your sig says you have a gasser. So you have lots of engine braking in the lower gears. I come down Black Mountain in 2nd. I start down 321 in 1st, and up shift to 2nd part of the way down, I start down 221 in 1st, and upshift to 2nd after the top 2 miles. I come down 226 in first, all the way down in 1st. I also do 16 in 2nd.
You didn't say which road you will come down. The interstates are easiest. They have the same max grade % all across the US.
Been down all of these with campers. 226 will take a few years off your life it's so stressful!! The rest are a piece of cake.
Better to start low and upshift than vise-versa.
