There’s a lot of mountain 2 lane driving between Silver City and springerville.
But you knew that.
What are you towing with?
Just make sure your trailer brakes are in good order, take the downhill grades slow from the top, don’t ride the brakes, keep tens downshifted where you’re in the 3000rpm + range for engine braking and despite what some will tell you, when you need to slow down on down hill grades, get into and out of the brakes quickly rather than minor braking more often. Longest time span you can provide for brake cooling between applications is the best.
Good trailer tires aired up properly as well. It’s hot out...
It’s a beautiful drive though!
