We are soon going to be taking our 07 Denali on a large, 4000 mile road trip. She has 130k miles and I'll be pulling a 6500 lb trailer.
Here's what I've done so far:
1. Replaced rear shocks, and compressor
2. Installed rear helper air bags
3. Installed secondary transmission cooler
4. Oil change + lucas stabilizer which has dramatically improved the likelihood of stabilitrac/traction control codes. However, it still happens periodically when running at high RPM's up the mountain followed by low RPMs / stopping.
5. (edit) Up' d the air pressure to 38 PSI instead of the recommended 34.
Things I haven't done but am considering:
1. LT tires. My P tires seem to have adequate tread left and so far I haven't really had a problem pulling the trailer with these tires, but I bet LT would be way better.
2. Drain/fill transmission fluid. Some say not to touch the fluid at these miles, others say drain/fill is ok, just don't flush.
3. What else am I missing?
Thanks for any advice!
