Elevation makes a big difference, especially when you're comparing a NA engine to a turbo engine. The rule of thumb for an NA engine is that you lose 3-4% per 1000 feet. No biggie at a couple thousand feet, but go to 6,000 or 8,000 and that starts to become a pretty big factor.
Ford states for a NA engine that loses 3~% of it's horsepower for every 1000 feet of elevation, GCW should be reduced 3% for every 1000 feet of elevation. Makes sense to me. The average 10k lb 5th wheel shouldn't be a problem.
