My, my, my it's been awhile since I checked in on this thread! Best of luck on the cross country trip! I need to get a build/resto thread going on my wife's Escalade since your build threads inspire as always!
Thanks!
I'm sitting in Montana right now. 2500 miles without any major problems. I do have a vibration at 80 mph and up though. The speed limit in MT is 80, so its a bit annoying. I did hit 100 mph a few times passing some ******* truck drivers. I gotta say, a tuned 6.2 hauls ASS!
I'm thinking the vibration might be old shocks or driveshaft. I need a new driveshaft for my HP goals, and I'll slap on new shocks when I get back.
