Longest one way, perhaps, but in 2009 I dragged a 5,000 lb travel trailer from central Virginia to Sioux St. Marie, MI, to Seattle, WA, via US 2, across the Olympic Peninsula and down the coastal highway to Los Angeles, then back east via I-40 through Memphis, TN to the starting point. About 9,000 miles round trip. Then in 2011 I dragged that same trailer from central VA to Las Vegas via Denver and St. Louis, made a loop around the Grand Canyon, stopping off at Bryce and Zion, then back to Virginia. About 7,000 miles all told.

So, to answer the OP's question, yes, several of us have done it, and several times. What is your REAL question?

Gone from SC to CO to UT to NV to CA then home thought NM TX and LO. All without any issues except a hose clamp letting loose on one of my boost hoses. And I started in Myrtle Beach SC so there to Huntington Beach CA constitutes coast to coast. And I added armor mid trip and wheeled it for 4 days in Moab UT. And the only casualty of the whole trip was my rear ABS senso on top of the axle. Mine ended up being 11k to 12k over a week and a half after all was said and done. Got the exact number from the GPS some where but can find it right now.

Logging freeway or state road miles coast to coast doesn't impress me. I took two trips to the farthest outback of Death Valley this spring. Total miles around 3k miles.

It's possible to get far enough away so that nobody would find your remains for a long time.

Lived in Moab 8 years. Steel Bender = Flat Pass. Nobody. . . does the loop from Flat Pass/Ken's Lake. . . takes in the step up at the cattle guard and exits on Westwater Drive in a Liberty. The single exception might be TJKJ.

Hell's revenge = Moab Slickrock Trail and with a little more torque, my '78 Rabbit could do it.

I'm going down to four corners soon, and plan to get just as far away from people as the tracks will go. I'm not concerned with breakdowns.

the thread was turbobike asking about long trips - no indication that he wanted to go offroad.

I added that because a lot of folks down in CRD land forget it really is a Jeep and there's a LOST Moab trip just about every year.

and yes there are harder trails in Moab and Colorado and even a few in Texas - but overwhelmingly the folks who do great at those - trailer their Jeeps in - very, very few - can or will drive 1200+ highway miles - run Steelbender and then drive 1200 to get back home.

Liberty's can.

(and the point of the exercise was to get to a 'Moab Slickrock Trail' don't see any issue there)

I carried all of my grease with me on a cargo carrier--- 500# of it. That was about 50k miles ago. And it still runs great. As I recall we used about 7 gallons of diesel, the whole trip was about 2500 miles.

ORM, EHM comes out in front of the passenger rear tire. Wife has new job and 20 mile round trip to work. I borrow her Jeep a lot and live in South Florida.

Currently in Calgary on our (non-Jeep) cross country trip to Alaska. I have seen quite a few Libertys coming south with Alaska plates, and at least two were CRDs. So I can report that people seem to consider it a good vehicle for a cross country trip. I've also noticed a few being towed by motorhomes. I think having the transfer case with a neutral position makes it a good vehicle to tow.
