2021 Ford E 450 chassis upgrade

Ive been reading about the new 7.3 liter Ford gas engine coming out. I was on the phone with a Ford Motorhome rep yesterday seeking information. From my understanding, the E450 chassis will be upgraded with this new engine and better brakes along with possible other improvements starting in the 2021 model year which comes out this fall. I was never a big fan of the Ford chassis suspension or the V10 motor. Furthermore the cabin is so tight and I am only 5'9. I hope that Ford addresses that issue as well. Does anybody else have any insight on this new chassis coming out ?

So will the E-350 retain the V-10 engine and 6-speed automatic?
We have been hearing that the doghouse on the V-8 is smaller, because the engine is smaller on the outside, and bigger on the inside (sort of like the TARDIS?). WE have also heard that the V-8 will produce more power, and also has a 10-speed automatic.

I found on page 71 & 72 of this brochure that the new V-8 engine entered production last month, as a 2021 model. Both the E-350 and the E-450 will have the new engine, but it appears the automatic transmission is still a 6-speed. I have the 6-speed, and it seems just fine, with even splits between the ratios.

Yes, that is my understanding also. The motor will have higher horsepower and more low end torque along with better MPG. I was ready to purchase either the 25B or 22M until I saw this news. Hopefully, it will be available in the fall without delay.

My guess is you'll never see the 10spd in the E-series because it won't fit the chassis floorpan area. Just a guess obviously

Even if you wait until fall to buy a 2021 model year RV it will most likely have the "old" chassis. Usually the chassis is from the previous model year.

My 2011 Reyo has a 2010 Sprinter chassis. It was the same with my 06 Sightseer which had a 05 Workhorse chassis. Maybe if you buy later on during the 2021 model year you have more luck.

I personally would not get the Ecoboost engine, too many problems.

I called Lichtin Rv in regard to this. Henry called me back and that from his understanding after talking to Winnebago ; this new chassis will be on their motor homes this fall. I hope it’s true.

I would caution y'all to not buy a first year Ford motor. I've been down that road, with Ford eventually having to buy my truck back from me. They have quite a bit of history the last 15 years or so of having issues with new truck motors. I'd suggest cutting yourself a break and letting someone else work the bugs out of it.

yup I am on Ford sites and that is so true. My friend just lost his engine on a eco boost Ford F150 with the V6 ecoboost. There are some inherent design issues.

The 2021 E 350 / E 450 chassis will have the 6-speed-automatc. The cab interior will be similar to the Super Duty series. Optional Ford offers now adaptive cruise control, lane assist etc. Guess that the RV-industry will use the new chassis for the 2021 models, perhaps for the 2022, due the fact, that they buy their chassis a year in advance.

There will also be a less powerfull version of the 7.3L V8 which runs on lpg, replacing the 6.2L V8.

I was on the phone with two different Coachmen factory reps. Both confirmed that the new Ford chassis with the 7.3 engine will be in their motor homes later this year. The dealers don’t want to promote this information because it will hurt the value of their current inventory.

just bought a 2021 Spirit 25B yesterday with the new 7.3 gas V8. Very responsive with quick acceleration. A bit loud under hard acceleration. Family friends own a large Ford truck dealership. Say the new 7.3 gas has been trouble free so far.

So far, so good with my 2021 25B on the Ford E450 with the 7.3 gas "Godzilla" engine.

PROS:
Better performance than the old V10 and a bit quieter inside the cabin. Appears to get slightly better fuel mileage. Very happy with the front & rear disc brakes and the tire pressure monitoring feature. Overall exterior and interior fit and finish is good - so far, appears to be high quality construction.

CONS:
Rear square tube storage bumper cannot accommodate a sewer hose because the bumper bracket bolts protrude into the tube and cause a blockage.

I have a big problem with the fact that Winnebago knowingly installed a Sony touch screen audio system that is not compatible with the Ford steering wheel controls. In my opinion, Winnebago ignored Customer Satisfaction by intentionally delivering a product with an obvious flaw.
Repeated calls to Winnebago Customer Care has produced no acceptable resolution. More troubling is that my dealer has also reported receiving unacceptable responses to the problem from Winnebago.

Hi Steve,
Good report. Please keep us posted on how it goes with the radio. It would be nice to see a photo of your dashboard.
Everybody has the same bumpers. I put my sewer hose in a Rubbermaid bucket with a lid on it.
Does Ford recommend Premium fuel for your V-8, as they do with the 2019 V-10?
Welcome to the Forum.
Thanks, Eagle5.

I've never heard of any such recommendation with the Ford F53 Chassis for any model year. Where have you heard this?

Here's what the Owner's Manual says. 87 Octane is the normal recommended fuel:

Quote:
Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. We do not recommend
these fuels.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer.

Hi Creativepart,
Your quote above is exactly what my owner's manual says too, for a 2019 V-10 E-450. Yes, Premium Fuel is recommended, but not required. I notice the onset of knocking rumble when I did have some 87 rating fuel in the engine. I like the slight increase in smoothness the Premium offers. I believe the timing is also optimized for increase power and MPG on the higher octane fuel. Should I change my moniker to Eagle91? (ha-ha)
Thanks, Eagle5

To each their own Eagle91.

I tend to read this as:

pump (R+M)/2 octane rating of 87.
So, that's what I use.
