Hi Everyone. Well, after 15 years the RV-Dreams Community Forum is coming to an end. Since it began in August 2005, we've had 58 Million page views, 124,000 posts, and we've spent about $15,000 to keep this valuable resource for RVers free and open. But since we are now off the road and have settled down for the next chapter of our lives, we are taking the Forum down effective June 30, 2021. It has been a tough decision, but it is now time.
We want to thank all of our members for their participation and input over the years, and we want to especially thank those that have acted as Moderators for us during our amazing journey living and traveling in our RV and growing the RV-Dreams Family. We will be forever proud to have been founders of this Forum and to have been supported by such a wonderful community. Thank you all!!
I am getting ready to purchase a used 1 Ton F-350 dually. My question is, how many miles is too many miles on the engine? 50,000, 75,000, 100,000? Any advice will be helpful. Thanks
Hmmmm...you look at some of the forums with posts bragging about buying an extended warranty and having big problems at 50k....with the turbo, with the....

"Yep, we wish we would have had one on our truck. Lost the engine on our 2005 Ford truck in 2012 with only 60,000 miles but it was out of warranty on time. Cost to replace was $17,000. And there is at least one other couple on this Forum that bought the extended warranty and also lost their engine. They were glad they had it.
I'm with RonC on this one - no, for small items, but yes for big ticket items unless you can self-insure comfortably."

If you're looking at the 6.4L or the 6.0L yes buy the warranty.
X2^^ - though I wouldn't consider the 6.0 or 6.4. We recently traded for a very lightly used (28K miles) 2012 6.7 - and I still bought an extended warranty.

In the opinion department, I really would recommend a 2012 or later for the Ford products. There were significant, positive, changes in the Ford engines and transmissions in 2011. The 6.7L is a totally different engine as is the transmission coupled to it. I suggest the 2012 or later as I, personally, always want a product to be in production at least one year after introduction. As to mileage on the engine / truck, naturally the lower the better. While many will say the engines are good for 200K (or so) I really wouldn't consider a 100,000 mile truck extended warranty or not. But that's just my opinion.
It's not necessarily the miles but how it's been treated and the quality of the fuel put through it. I know of two individuals who have 1999 F-350's with the 7.3L that have over 600K on them. Water in any amount in the fuel is one of if not the largest enemy of diesel engines. Allowing them to cool down before shutdown is another. Just remember that turbo is turning around 100,000 rpm and when you shut the engine down it has no oil to the center bearing between the hot and cold sections. Let it cool down and slow down before shutdown. Clean fresh large volumes of air are another. Consider a by pass oil filter to keep the oil cleaner too.

If one wants to go all the way back to the trusty 7.3L - that's kind of a different discussion. :) But trucks that old, 1999, can be great but also have other issues.
But to your points, absolutely, let the turbo cool down. This is a most critical point in a turbo's life. Read the manual. Some manuals indicate a 5 minute cool down when under heavy loads, such as towing. When running solo under light loads, a minute or so does the job. Shutting down a diesel "hot" or starting to pull a heavy trailer with engine cold can do serious damage in the long run regardless of mileage. So if the previous owner did not treat the engine with respect issues can and will develop.
While diesel's are very powerful, they are also quite "touchy" about how they are treated. Good points.
The old 7.3's were good engines, they don't have near the power of the newer engines, the 6.0's are junk unless you spend the money to have it Bullet Proofed. the new 6.7's are great engines
