SENORS SPENDER
 Had a good run with it until 80k then the check engine lights starting glowing bright. O2 and knock sensor failed. Knock sensor lives inside the engine so yeah, big repair bill. All said and done it was a $1200.00 bill to fix two stupid little "make your engine run fun" gadgets. I can out run it on the onramps but, I'm not considering that a big deal. I finally got to where it needed brakes at 75k - I thought that was incredible! All in all, it's been pretty good. Hope to get another 80k out of it. Truck still drives and rides like it did when it was new. No problems outside of what I mentioned earlier
