I live in Colorado Springs (6000') and will be camping as high as 9000'. As posted in my earlier thread, my combined truck and trailer weigh 9380 lbs. If you follow the Honda Ridgeline owners manual guideline of reducing GCWR by 2% for every 1000' of altitude, then at 6000 ft I should reduce my GCWR by 12%. That puts it at 8877 lbs (10,088 lbs * .88 = 8877 lbs). In other words I'm technically over the limit at my house, never mind driving up into the mountains. So...
What exactly is the Honda guideline pointing at -- the fact that the engine loses so much power at altitude that it simply cannot pull very much weight? Assuming I go anyway, and keep my speed down so that I'm not revving over ~4000 rpm, do I *really* need to worry? Of course I may be taking some lifespan out of my motor, but so be it.
Just curious what the real-world restrictions / concerns are when it comes to towing at altitude. And no, there are no turbo kits for Honda Ridgelines so that's not an option
