Holy crap---that's about 300 miles a day. You must do a lot of highway driving/commuting. Any issues with the truck?
I'm on my 2nd exhaust manifold, OE had 190,000 and aftermarket tubular steel cracked after another 100,000 miles.
Alternator went at 290,000 miles. No sweat though, amazon.com same day delivery of ac delco replacement for $124.34
Horn stopped working, I hit it a lot.
Changed factory brakes at 223,000 miles. Could see reflection of tools in rotor, didnt need to cut.
Check engine light is giving P0420, prob due to cracked manifold.
No other real issues. Just change oil every 2 weeks (3800 miles), trans and differential fluid every 50,000 and it pretty much runs forever.
I do have to say the starters are awesome, I start mine up like 20x a day and got almost 500,000 miles (5 years) of use out of it before it quit.
As of today, 291,000 miles. Thats 897,892 miles on two Canyons since April 2006.
