I just ran mine to CO Springs from Newport Beach CA, and got a service Suspension light in Aspen Vail area at top of pass. Turns out (as the CO Springs dealer said) the truck never had a high altitude software update and should have. They figure the low density air caused a sensor to over work and blow out (we were at 12.5K feet at one point) they replaced the sensor and did the update and no problems since.
