Road trip! Sounds like fun. The reality is a lot of hours driving on the interstate in a noisy Jeep.

So, when are you going to do this, and how much time do you have, Andy?

Hopefully, you've resolved the vibration at highway speeds you discussed. I suspect regular highway tires in good condition would be best for this type of trip. If you have air conditioning, it would be a good idea to have it in top operating condition for the areas you'll be traveling.

Also, it wouldn't hurt to flush the cooling system and consider possibly replacing the water pump and thermostat.

Such a long trip! Mostly through desert out west; pickup truck areas! You'll be the lone Jeep on the road, most of the time. You'll know you're in a four-wheeling area when Jeeps are more frequently sighted on the highway!

It would be great if you could hook-up with some wheelers in Albuquerque, Flagstaff, Kingman, and Barstow, I suspect. I can't believe your traveling this far west and not four wheeling in Colorado and Utah(Moab)!

Hey, have a great trip. I think you're smart to consider preventative maintenance on your Jeep before you start your trip. I'm sure others will have some great suggestions beyound normal oil, lube, & filters. Go prepared.
