How many miles on DPF

For the guys that have NOT deleted your trucks and rack up the miles. How many miles did you get before the DPF was full of ash and needed replaced / cleaned. So far I'm at 111K miles and still going strong. I have read that the life expectancy is around 120K miles. I'm considering deleting my truck but I drive it for work and I have to replace it with something next year. I don't have to have a truck for work I just prefer to drive a truck and we have a 12K lb 5th wheel so I need to have a truck in the stables. If I delete it then I'll be married to it for a few more years and have to buy a car next year then do the driveway shuffle with the extra vehicle in the driveway.

What year is your truck? I know a few on here that have >200-300K and DPF is fine. There is no requirement for cleaning on the 4th gens with DEF.

There’s guys on here that have gotten well over 300k miles on their dpf and still going. I’d say roll on 18 wheeler...
387K so far.

And, you can get the DPF cleaned now for around $300-$500, so no need to replace them.

But, like many things on these trucks, how quickly they degrade, dirty up, or whatever, depends on how they are used. My truck sees almost 100% highway miles and very little idling time.

I’d love to see your source(s) of the 120,000 mile DPF life expectancy.

The ol’ 2014 RAM 3500 Tradesman Crew Cab 4x4 had 362k on it at trade in time. All emissions items were in working order with no CEL’s.....

Thanks for the replies guys. My truck is a 2104 (in my sig) and it gets used in mixed driving as well as a little towing. I'm at a little more than 10% idle time if the EVIC is to be believed. The Edge CTS shows when I'm in regen and I probably regen about once every other tank of fuel or so.
just traded my 2015 with 300,000 and original DPF on it. Had a new SCR replaced from some recall around 190,000. Other than the 1 limp mode at 190,000 and the SCR replacement, no problems from the DPF and related crap.

45K, but I guess that is not what you are truly looking for. On various forums and FB pages for RAM trucks I do not think I have seen a post about the DPF truly needing to be cleaned or replaced. Many about a 100% full message but seems like a good hard highway trip always fixes it. I am curious if anyone has had to have it replaced or removed and cleaned regardless of miles, if so it is an extremely rare thing.
I think these emissions systems were designed/rated to have lifespans that roughly corresponded to the engine's B50 life (350k miles), though some on here have proven that these systems can potentially last longer than that.

If you're doing longer trips and/or carrying heavy loads every so often, I really don't see why the DPF would need replacement/cleaning for at least several hundred thousand miles.
Thanks guys!
