Don’t know anything about that engine by that name but a quick google search and it’s the 6.4 Turbo diesel out of Fords from 2008-2010. I’d stay away. Those year Ford diesel’s were nothing but expensive headaches.
It looks like they used a very different turbo setup on Maxxforce and reduced HP by ~60% from Ford version. Same torque though. I have no idea whether those changes improved on the 6.4 issues.
OP, are you trying to sell a Maxxforce that is giving you issues or are you looking at a new RV with one in it?
looking at buying one, it's a 2011 tiffan alergro breeze 28rb. i'm trading in a c class
Damn, RV's make bike insurance look cheap. Good luck with your search.

It was mostly related to emissions. If you deleted and tuned them from new they weren’t terrible. I’m probably going to butcher this so don’t quote it. The way it was explained to me from memory the regen process to clean the diesel particulate filter on the 6.4 only used the 7 and 8 cylinder to send unburnt fuel directly to the exhaust to burn it out. This washed the cylinder walls and you were in for a engine replacement.
There was a number of other issues as well but that was a big money problem. EGR coolers, head gaskets, and other odds and ends.
Cheap bastards. If raw fuel is required in the exhaust stream for regen, they should just stick an injector there.
You may want to do some more research. The Maxxforce and ford seem to be siblings (almost twins).

reads like MaxxForce was the re-branding effort for the old DT Navistar engine
didn't work as the Maxxforce has been discontinued as well
as for the DT's
complete disposable garbage
don't like cold
really don't like ether
any medium duty truck I've dealt with that was DT powered spent most of it's life tagged out
junk

I know the 6.0L ford had a lot of problems, didn't think the 6.4l had them. been out of the auto game for awhile so i'm sorta blind here, don't want to read to much into the info i'm seeing on some of the searches i'm looking at
Had a class 7 tractor I drove for a period of time at work with a Maxforce. The thing had more days in the shop than it did on the road. Fleet HQ apparently had strong words with Navistar over the debacle trying to claim lemon law on them. They're all gone from the fleet now and it left such a bad taste in the companies mouth that they've never bought another International tractor since.
Take that as you will coming from a company with thousands of pieces of equipment.

That should have been a big maxxforce that had almost nothing in common with this one. That being said, if the company gives grief to a fleet, imagine how little help an end user would get.
At one point there was some class 6 and 7 trucks used commercially that did have the same engines used in consumer level equipment, so I wouldn't be so sure. We have some class 7 Freightliners right now with 4 cylinder diesels used in much smaller vehicles as well. It's only the class 8 stuff that gets into the big displacement 6 cylinders.
