Hmm... you guys on the 3rd gen side are getting soft, letting something like this get by with NO comments:
I know if I start getting "Gas" milage, it will be good, just the truck thats hauling it will do poorly.

I have an 05 that just stroked 30k....not one problem with anything at all ....GOOD LUCK

p.s. this is my 5th one....no complaints at all

 

7500 miles since april 1st. and so far all is good. Knock on wood.

 

Just turned 1K on mine...too early to tell but seems quite solid I am averaging 15-16 mpg this should get better as the engine breaks in.
