engine longevity?

I'm betting 99% of Motor Homes that go to the junk yard due to the drivetrain issues...it's the drivetrain rotting out rather than wearing out.

You see the same thing in cruising boats.

Almost no one wears out engines in a leisure vehicle.

I agree 100%.

It is very concerning if you see rusted brake lines. Another indicator is if you hit the main frame just forward of the rear tires, with a hammer, and it showers down rust, I would stop right there and kindly leave.

We live near Chicago where salt is used on winter roads. Our rig is stored in our heated garage during that time. I bring it out well after the spring rains have washed the salt off the roads.

It would be different if we were snow birds or winter campers. I would not let that get in the way of enjoying our rig. But we use it seasonally anyway, so it is easy to apply best practices. If we ever sell our rig, it will be a "Hot Buy" for the like-new condition it is preserved in.

Many of those may have been used by weekenders or drive2sit, so the mileage appears low for the age. The RV may be well used just not through miles.

I have a 94 GM 350-TBI paired to a 4L80 tranny. Mileage is over, well lets just say I'm thankful I only need to complete one odometer turnover affidavit and not one for each event! I do standard and enhanced PM on it and have only needed to change the oil cooler flex lines due to seepage and the oil pan due to a rock. Still goes strong with no leaks, squeaks or parts falling off.

A Class C is built on a commercial truck frame with an engine an transmission designed for commercial use. 100K miles is NOTHING if it is properly maintained.

RUST is the enemy. If it was bought and used in the mid-west or northeast, after 10 years you have to watch carefully for rust destroying brakes lines, wiring, etc. etc.

The answer is NO. The Ford & Chevy engines & transmissions go much longer.

If it was not that you joined this group in 2012. I would have thought this question was a troll.

B10 for the V10 is 450,000 miles. That means by that mileage, 10-percent will need major repair. They do not exclude abuse or extreme use cases from this. This is better than all of Ford's diesels after the 7.3L.
