Good news all around guys - thanks for the advice. Picked up a 97 Expedition as a weekend warrior last week. In the shop now for fluid changes, plugs and a wheel bearing - but it has 130k on it all in all seems in pretty good shape.

I have a work truck I drive that has 255k on its 5.4 ...untouched so far except normal maint.

This was a HUGE deciding factor when I chose an Expedition over a Suburban. I do think the 350 Chevy engine will run 200k miles but those 95-99 versions I was looking at usually need a tranny right on cue at 100k miles. The 4r100 behind the 5.4 in my 99 Expy is similar to the ones behind the Super Duty trucks. I definately have more drivetrain than I need, I like it that way.

My friend Mike has 375k on his CrownVic cab (former municipal car), original motor still smooth, doesn't burn any appreciable oil. On an aside, still somehow has the original transmission although it hunts around in and out of OD but still shifts tight.

177K on an 04 4.6 E250, 172K on a 00 5.4 Expy. They both run extremely well. No major problems and routine maintenance. I run Max Life oil and change every 5K. They run like they day they were new. Honestly. Gas mileage has not changed. I have replaced the plugs in the 5.4 but that's it. I think I will do the 4.6 plugs this winter. No plans to get anything new. Just keep driving them. Great friggin motors.

What motor oil are you using? While mine was under warranty I let the dealership do the oil changes, and of course they use the Motorcraft semi-syn. I used (not leaked) about a quart per interval then. Now that it is out of warranty, my trusty old mechanic does all the maintenance. He keeps conventional Chevron Supreme or Havoline on the shelf and usually uses the Chevron. Since then the oil level shows on the dipstick at the same level throughout the entire oil change interval.

That tells me all I need to know about those trucks, as well as my own personal experience when I jumped on the Z-71 bandwagon a few years ago and had some issues with the "almighty 350".
I have a Tahoe with a 350. It has 180,000 miles on it. The automatic transmission and engine have not been rebuilt. It runs fine. You are only noting the trucks for sale. The ones with the high mileage aren't for sale.

I bought this '10 Ford to replace my '86 Chevrolet P/U with 230K miles, original engine and transmission without rebuild and ran fine. I sold it because the cab was falling apart because of rust. I'm a Chevy guy. The only reason I bought a Ford was because Ford offered a manual transmission and I wanted to shift my own gears, having a blast double clutching while downshifting like the old big rigs. I'm counting on the rest of the truck to hold up like my Chevys do.
