Just like the topic says my truck is a 99 been trouble free so far it has 275k on the clock and still getting it. what kinda milage do yall have?

mine had 278,000 on it when i swapped to the 6.0. Ran strong. 10.0 in the 1.8th all stock. lol

187,xxx on mine.

my dads has 272,xxx on his.

My 99 has 86,000 and still runs like new...

Mines just a baby at 123k. Put the blower on around 100k, and put the cam in last weekend.

Replaced:
1 hub
shocks
steering box, inner/outer tie rods, pitman arm, idler arm, idler pivot
A/c compressor (not cheap :( )
Rebuilt trans (due to terrible tune by wait4me)
passenger front speaker

I know there's more but drawing a blank right now

Hey duramaxxin! Good to see ya around!

300,000 aint sheet on an LS engine!!

My truck had a 183,000 mile 5.3, when i pulled it and looked at the cylinder walls they still had cross hatching!!!

A lousy 115,000, just got back from trip to N.C. (1300 miles round tirp) 17-19 mpg with 5 people 70-75 mph, and a load of crap. Truck still all stock.
