My 07 Envoy 4.2 2WD is approaching 100k miles. It is my daily driver and tow vehicle on the occasional weekends. My camper comes in about 4000lbs fully loaded.
It is currently running fine, but I am concerned about future reliability.
Any input in future problems I could experience?
How well do yours run after 100k miles?
Thanks in advance

I think if they are well taken care of they are very reliable. There are various sensors that occasionally go bad but I'm just over 100k and I expect it to last a long time.

If you don't have one, I suggest you get a tranny cooler since you tow the camper.
Keep your fluids changed, throttle body cleaned and it should last a long time.

Agreed. Tranny cooler. All fluids including rear diff at 100K, plus spark plugs. Only use Delco 41-103.
