Ford Dealer Service Manager Says the Fuel Filter is good for the lifetime of RV

Ok so I went to the Tillmaook Oregon Ford Dealer Service Dept. and spoke to the Service Manager asking for a Ford Fuel Filter so I can change out in at 30K miles. He says do to the fuel tank having a filter with a second inline fuel filter there is not need to change the inline filter for the lifetime of the vehicle. I got my owner out and he and I both looked it up and there on page 290 it confirmed it. What is your experience. It was my understanding it should be changed at 30 and 60K miles. Im thinking I will order one on line and have it handy and do the the replacement my self at 30k ..  I have a F450 V-10 6.8L

I didn't change fuel filters on any of the RV's (Ford E 350 or 450 cutaway) on any of the RV's I have had.  The one (so far) that had the most mileage was a 2000 Winnebago Minnie that I bought new and traded 9 years later at 69,000 miles on it.   Zero problems.  I traded the Minnie on a new 2008 Forest River Lexington.   Traded that on a new 2015 PC 2551 and the Lexington had about 60,000 miles on it.   My PC now has 50,000 miles on it. 

Oil change shops like Grease Monkey don't always tell you their service recommendations are "suggested" service, not factory recomendated service.   They also assume every vehicle is used in the worst conditions (short trips, stop and go traffic) vs best conditions (highway miles with very few stops)

I worked in the shop that maintained the FPL (Florida Power and Light) trucks, and many were F150 with the 5.4l , which is the 8cyl version of the V10 in ours.

We never put a fuel filter into one of them, wasn't even on the maintenance checklist which went to 100K miles.

 I just think it prudent to change and or inspect the filter periodically due to the possibility of contamination with traveling across country and receiving fuel from many different parts of the country a ounce of prevention is worth a pound of cure  especially if you’re out in the middle of nowhere  at the very least I’ll carry a spare with me that way I will have it in case I need it

It has been a very long time since I changed the furl filter on the E series and perhaps the set up has changed but I recall the little release tool that you had to use on the pressure fittings was a pain!   Make sure you have that tool!

There's nothing to inspect in today's fuel filters.  They are a closed can with a short pipe at each end.  Nothing like the long ago sintered brass filters that went in the carburetor inlet.   

If you feel better changing them on a schedule, that's fine, have at it... Your peace of mind has value.
