I don't know the incidence of fuel pump failure with "older" E-450s, but I sure hope that the pump in my tank doesn't go south any time, let alone when I'm on the road. (Provided that I ever get that opportunity again!) I do replace the in-line filter every 15k miles (or close), never let the tank get below about 20 gallons to keep the pump sock "immersed" in gas, and the tank is always "full" when the rig has to sit. I think I'm doing the right stuff to ward off a failure, but sometimes  one is the pigeon, and sometimes one is the statue!  ;)

Hi Greg.  Interesting things pop up on YouTube and  a search for "Ford V10 sounds like a can of marbles being shaken" yields all sorts of things from 'thats normal' to outright 'disaster'.  I watched a video on a smaller engine, but the same modular triton as our V10.  https://www.youtube.com/watch?v=EPFv0veBO8k   about the 5:15 mark, to give you a good scare.  
    So Larry, you've heard this? On the engine you have now? My engine is the older V10, the 1997-1999 model. I haven't heard it (yet).  I do use the Mobil 1 5W30 as stated on my firewall sticker.

Thanks for that, Ron. That is a similar noise but luckily I haven’t heard it at engine idle. I noticed it when I was cruising between 2000 - 2500 RPM, usually going up a slight incline, or when accelerating.  However, sometimes it would just start doing it on its own for a while and then stop. Going to get a smog check and DMV registration on Monday so will try and record the noise and perhaps email it to one of the engine gurus on the forum. Also, on Wednesday I am taking it to an RV/automotive shop in Lancaster and will have them change the oil and go through everything.

Regarding a rattle-like noise, if it's not a ping (marbles in a can-like sound that happens only under load), look at any heat shielding on the front end of the engine exhaust plumbing to see if it might be a little "wiggly".

On the trip back to California from Florida, I noticed a noise from the engine area.  Hard to describe since my hearing is not the best but it was a type of rattling noise.  It happened frequently when accelerating or going up a grade. 

About a year ago, I started a post "2017 MB: Strange Noises."  It involved three separate noises: creaking from the suspension, a droning/humming from the transmission, and a ticking noise from the engine.  The ticket noise from the engine only occurred between 65-70 mph and stopped whenever I let off the accelerator.  I tried a higher octane of gas during a trip out west, but still had the ticking noise.  I found a Youtube video "Ford 6.8 V10 Triton ticking noise" - https://youtu.be/fSmXgaxR3AA - that had the exact noise.  The person tried recording the ticking noise, but the engine noise is too loud.  I could hear it when I listened with headphones, specially at the :40 mark.  I also posted my experience there as well.  I took my MB to a Ford Truck repair place and they determined it was a faulty alternator and replaced it under warranty.  I took a trip to Florida and the ticking noise came back.  I returned from Florida and went back to the repair place.  But found out in the meantime that they stopped repairing RVs.  I took it to another repair place and they determined it was a faulty Serpentine Belt.  They replaced it.  I have since put 5,000 miles on the MB and the ticking has not come back.

Thanks, Glenn, that does sound like the noise. When I take it in for service on Wednesday, I’ll mention that to the service writer. 👍

Our ticking noise was from the idler pulley.  I had pulley and belt replaced and noise went away.

Glenn, looking and listening to the video again, I noticed that the noise in the video was occurring at the same range as mine, 2000-2500 RPM.

Greg, seems like quite a few E450 owners have experienced this issue. Here's a link to review my-triton-v10-sounds-awful .

Thanks for posting, Charles. Sounds like it could be a couple different things. Hopefully I can get it figured out when I go in for service on Wednesday. I did crawl underneath the RV yesterday to ensure that nothing was flapping around down there as far as I can tell.

To manually check the idlers, remove the serpentine belt and spin the rollers by hand, they should spin smoothly with no indication of roughness. If going that far, changing the belt isn't a bad idea.

Turns out the noise was the serpentine belt. Now I have a shiny new one and the old glazed one is an emergency spare.  Thanks for all your input!

I was feeling pretty good as I was able to get several things done today, including the smog and California registration, then when I was almost home the “service engine” light came on. Arghhhh!   I have a code reader so will try to see what’s going on tomorrow. It’s always something, isn’t It?

I may be dating myself but I remember from some time back that you could buy a 'belt dressing' to quiet a noisy belt, no??

Probably true but the service advisor made a good point: the serpentine belt controls everything and if it goes, you’re out of business. Since it was almost 4 years old, I decided to play it safe, and now I have a spare!

"Since it was almost 4 years old..."

So, if I understand where you're coming from I guess I should change my sixteen year old belt?   :D   :(

Your serpentine belt is living on borrowed time, how about the radiator and heater hoses, are they original too?
When the belt is replaced, make sure the mechanic check the condition of the idlers, fan clutch and water pump bearings.

My 2004 E450 Scheduled Maintenance Guide shows an inspection at 100,000 miles, and a replacement at 150,000 miles - no time limits specified. So, it seems like Ford thinks highly of it's belt. My belt is 16 years old, 60,000 miles, and looked perfect when I examined it recently. Is there any reason to think the listed intervals are too long?

Age as well as miles causes the belt to slowly decay.
Inspecting the belt for glazing on the smooth side and cracking between the teeth on the other side, when bent backward, is suggested annually.
