I have a 2005 Yukon XL, currently with 233K miles. In Pril 2021, we left for a 7500 mile, 5 1/2 week trip. The Yukon had about 197K on it then. We left VA, drove to Chicago to get on Historic Route 66, and did the entire trip all the way to the Santa Monica Pier. We came back through Las Vegas, Utah, Wyoming, then on back home. I took a toolbox and a scanner, but never had to use them. I would change the belts, but it sounds like you have covered all the bases otherwise. Enjoy you trip!I’ve got a 2010 Tahoe LTZ with 144k miles and wondering if I should take the this car or rent a car on a 3000 mile road trip this summer. I do all the basic maintenance; Mobil 1 oil, already changed power steering fluid, flushed brake fluid; tranny and radiator flushed; all spark plugs replaced. Has original engine belt, starter etc. It has been very reliable since bought new. Just finished a 1000 trip no issues. If I take this Tahoe, what preemptive service or part replacements are recommended?
BTW, in the fall of 2021, we drove up the East Coast to Bar Harbor, ME, and back home to VA- over 3K miles. We had no issues on that trip, either.
