I've been preaching this for a few years now.

Ford towing guide, last page...

High Altitude Operation
Gasoline engines lose power by 3-4% per 1,000 ft.
elevation. To maintain performance, reduce GVWs and
GCWs by 2% per 1,000 ft. elevation.

So, at 6000ft altitude, the 2010 F150 with the 5.4l is producing about 236hp instead of the 310 it would make at sea level. Thus making the maximum recommended GCVW at 15048lb instead of 17100lbs.

I just used Ford as the example as I was already on thier website. Same applies for Dodge, Chevy and Yugos.

Interesting fact: Turbo engines only lose power at 1/2 the rate of naturally aspirated engines as elevation increases. So at that rate, reduce GVWs and GCWs by 1% per 1,000 ft. elevation

Saw that a while back on the Ford website. My wife and I decided to follow that rule and now when we travel the 17 mile 6,000 ft elevation change to one of our summer getaway campgrounds, she rides in the back of the truck and tosses firewood out as we climb so we can compensate for power loss.

As long as after you set up camp, you go back for the wood. [emoticon]

Better yet, have her drive the SUV, haul the wood and 5 gallon jugs of water to fill the fresh tank when we get there!!

Or get a diesel. But then I have to get one of each brand to satisfy all readers of this forum. [emoticon]

Is that the wood you should not be bringing into a camp site? Ya know, the one with illegal alien bugs. [emoticon]

When you fly small airplanes you have to take this into account to see if you can get off the ground again at high altitude airports. You also need to take into consideration the temperature. For example: If you are at Big Bear airport in CA (6700') and the temp is 100 degrees outside (this happens), the air is as thin as being at a 10,000' airport. The same would hold true for any normally asperated engine.

Naw, just put a Cummins backed by an Allison into a Ford, then you'll be covered. [emoticon]
