I just returned from a 1,400 mile trip towing a heavy 5th wheel. My 2006 LBZ with 199,000 on the clock did great. My average mpg for the entire trip was 11.8.
What has been done to this truck other than normal fluid/filter changes since new? I'm sure I will forget some items but from memory:
Front wheel bearing assemblies
Steering section
Shocks
Brake booster
Transmission cooling lines
1 injector
XM Radio receiver
Steering shaft (3 times I think) and bearing/bushing (I forget which)
Climate control head
Headlight/dimmer switch control panel
Rearview mirror/window adjustment remote control panel
Expensive repairs, but the truck is paid for and it does what I need. The engine has never ever burned any oil between changes and the oil filter has been changed with each oil change at 5,000 mile intervals. The fuel filter has been changed 19 times with number 20 coming up soon. The Allison will see a fluid/filter change at 200,000 which will be the 7th change. Oil and filters are cheap.
New truck? No way and no DEF problems here.
