uggh did you at least get the Y-Pipe fixed? (Those first V-10's had a terribly restrictive Y-Pipe joining the exhaust manifolds together.)

The 362 HP 6.8 V10 uses 7 quarts of oil (F series owners manual page 112). Had to look to make sure my dealer didn't over charge me for an extra quart of oil during the last oil change. I can't remember what the capacity was for the 305 HP V10 in my prior Class C.

6 quarts for the E-Series V-10:

page 200.

I think that is because they had to squeeze it into the E-series and the oil pan has a few "kinks" in it as a result.

Yeah if you look at the F-Series, 7 quarts:

No, no chassis-related upgrades at all. I didn't keep that motorhome that long, and the power seemed more than adequate. It was light though at 11,500 pounds GVWR. Even when I towed 4,000 pounds it was plenty of power.

Fuel economy on the other hand was +/- 8 MPG, which is why I got rid of it. At the time it seemed wasteful.

Correct; both of mine also.


Another advantage to V8 should be slightly lower weight, thereby increasing cargo carrying capacity for a given GCWR. Although difference is likely insignificant considering how heavy motorhomes are built.

How about offering the 6.7 Diesel as an option on the F53. Its an option on the F59 along with CNG fuel option too....

I think it comes down to cost because the average gasoline motorhome doesn't get driven enough to justify the higher cost of diesel like on commercial vehicles. If a person wants a diesel because they want a diesel, then they don't have to justify anything. But I think most people prefer the lower-cost option when performance is similar.


By the way, talking of costs, I couldn't find any pickups where the V10 and 6.2L V8 are offered on same identical model in order to compare prices directly, but we can deduce by comparing each to the diesel that their costs are very close. That's to say that going from V8 to diesel costs about $8,500, and going from V10 to diesel also costs about $8,500. I would guess from this that Ford will price the 6.2L V8 and the V10 very closely. Who knows, the V8 may even be a no-cost option.

A different spin on Ford V10's future; which mentions Ford offering the 6.2L V8 in 2017 E-Series as one sign the end may be nearing.

As a little background, this is 2016 Ford E-Series GCWR with both the discontinued 5.4L V8 and the 6.8L V10.

As can be seen from these numbers, a motorhome with the 5.4L V8 that is loaded close to GVWR would have minimal towing capacity. Whether an E-350 or E-450, the old V8 didn't have much excess GCWR above the GVWR.

By comparison, preliminary 6.2L V8 GCWR is much higher than that of previous 5.4L V8.

At 17,000 pounds, an E-350 should be able to tow most toads.

I think the rating for the SRW E-350 is probably a misprint -- I'd bet it's also suppose to be 17,000 instead of 13,000 pounds.

Is Thor going back to the E-350 rather than the E-450 that my 2016 Axis is built on?

Ford today released more detail information on 2017 Super Duty. It had been reported that 6.2L V8 would be revised somewhat; as was the case.

For 2017 Super Duty the 6.2L gasoline V8 remains at 385 Horsepower, but torque was increased from 405 to 430 lb-ft. It will be very interesting to see how Ford rates the same engine when installed in E-Series. For comparison, the E-Series 6.8L V10 is rated at 420 lb-ft.

BTW, incredible tow capacity for new diesel Super Duty.

Updated information from Ford states optional 6.2-liter V8 for E-Series will be delayed until January 2017. This is from 2017 RV and Trailer towing guide.

Will the V-8 really be available for Vegas/Axis? Everything says it will be available on the Cutaway chassis -- Vegas/Axis uses the stripped chassis. Is the V-8 going to be available in all E-series chassis?

The graphic Chance posted lists the V-8 as available for the stripped chassis (the middle column right above the note about availability).

Ed, I have no idea whether Thor will offer the optional 6.2L V8 on the Axis/Vegas. I agree with others that it's unlikely Thor will offer both V8s and V10s simultaneously (beyond period of switching over if that's what they do).


My track record trying to guess what Thor may do isn't great. I personally think they will switch to V8 if it improves fuel economy and if engine cost isn't much higher than V10. Noise level from V8 should be lower, and it should save a little weight, so why not?

I hope they switch to V8, but I'm normally wrong so I'm not holding my breath.

They could be economically forced to do so: By switching to the V-8 the mpg would likely increase for the Axis/Vegas units (as its a newer engine and more efficient than the V-10). In theory this may allow them to switch back to the E350 chassis (if the switch to the 450 chassis was driven by fuel economy it is logical that using the higher mpg V-8 would allow them to go back to the 350 one).

Of course all of the above is pure speculation.

It would be great if Thor simply offered that as an option: E450/V10 or E350/V8.

All decisions will be based on profitability for the manufacturer.

I agree we are speculating, but at the same time there is a lot of formal information to work with.

The switch from E-350 to E-450 appears to have been driven by emissions certifications. Both Cutaway and Stripped Chassis have frontal area and weight restrictions that don't apply to the E-450.

Ford recently updated 2017MY E-Series Cutaway / Stripped Chassis Frontal Area and Weight Restrictions, which now includes the possibility for E-350s to have frontal area up to 82 square feet (previously it was 72 square feet maximum), but only if body manufacturers follow aerodynamic guidelines to reduce drag.

Requirement for the Stripped Chassis on which Axis/Vegas is built on is much stricter than for Cutaways. The sketch for Stripped Chassis bodies to get to 82 square feet looks a little similar to an Axis/Vegas (not suggesting that was intentional -- just found it interesting). As I said before, I'm not even certain that motorhomes fall under these same guidelines; although I expect they do since they are not specifically excluded. Picture below:

Probably right except when government regulations are involved.

Advertised price for E-450 is considerably higher than that of E-350, which would explain why Thor used the E-350 chassis until they could no longer do so. Following that logic, they would switch back if they could.
