Dave, I suspect that is because you were running in a higher gear than the V-10 except on level stretches of the trail. When we were on a trip to Mexico led by Monica and Gary Wescott with several other SMBs, we drove down into the Copper Canyon a couple of times. The road was steep (and narrow). I was in 4WD, low range, first gear in our V10 while the diesel owners were in 4WD, low range, second gear. They were probably in a higher gear going back out too...
