Climbing in the Rockies
Have a question. I have a 3500 GMC diesel. My question I when in the mountain areas should I leave it in drive and use the exhaust brake, or put it in manual and shift gears when climbing and descend...

Unless you know the road, let the truck do the thinking in tow/haul mode. If you know the road, use the manual setting, because you can think ahead, the truck cannot.
The only time I needed the manual mode was on the million dollar highway north of Durango. The trailer brake controller died, and left me without trailer brakes. I used the manual shifting, just like Dad taught me to drive a dump truck. The gears are for dropping, the brakes are for stopping.
Here is another plug for the Ford dealer in Steamboat Springs for getting an out of towner back on the road.
