I have a 2008 Envoy SLE with 4WD. Bought it used from an older couple with 83k miles on it about a year ago.
First thing I did after purchase was take it to my favorite mechanic who said they had replaced 3 transmissions in TB/Envoys in the last month because they overheat, and recommended putting a heavy duty trans cooler in it, so I had them do that.
It's my first 4WD and I'd like to lightly optimize it for camping and light offroad. I also pull light trailers with it often. So far I've really only taken it out once - pulled a lightly loaded 5x8 enclosed trailer across a wet pasture on a hill to/from a campsite with no problems.
Thanks for letting me participate in the forums, looking forward to learning and perhaps sharing. I plan to build removable sleeping/storage in the back and have some ideas sketched out.
