A friend told me that they are getting 13-18 mpg with a V10 Ford engine in a 29 ft class c. That kind of blew me away for a minute, but this person is trustworthy if they're calculations are correct. So can somebody tell me if this sounds reasonable? Or what do these units get with gas engines and a length somewhere around 29 ft? Thanks

Seems pretty reasonable ...

Down hill with a tail wind!

(fwiw I have a friend with a Journey class A diesel who swears he gets 12-14 mpg. I have the same engine and know it ain't so)

There seems to a new math system when it comes to fuel economy. typical eco average is closer to 10. I have 2 riding buddies with sub 30 foot V10 Tioga's.

Most people use the lie-o-meter because they are under the impression it is "fairly accurate". That much MH he is lucky to get 8MPG.

Greetings,

8822.2 miles / 1307.931 gals = 6.745 mpg. (mostly with a Ford Escape as a frog)

I need to learn some of that new math!!

If I go by my onboard fuel economy readout, at times going down hill it shows 25 MPG, but in reality it only gets 7.5 MPG. It is not a V10 but you get the idea. It is all in the way you calculate fuel mileage. The best way is fill the tank full on a level surface. Write the milage down, drive your trip, fill up again on a level surface. write the mileage down again. Subtract the first reading from this reading to get the actual miles driven on this tank. Divide the miles driven on this tank by the gallons of fuel you put in. So as an example if you have driven 300 miles and it took 37.5 gallons to fill it up, 300 divided by 37.5= 8 MPG. Or if it took 40 gallons, 300 divided by 40 = 7.5 MPG. Do this on a few trips and then get an average. I don't beleive at all for a V10` that you will get 13-14, do you? More like 8 at the highest on a good day on level hwy. His math or method of calculations are suspect in my opinion. I know some people figure by using the gas gauge, like I went 300 miles and only used a half tank by the gauge. Well I have a 75 gallon tank and when the gauge shows half tank it takes 42 gallons to fill it. Now with a 75 gallon tank, half tank should be 37.5 gallons, not 42, so the gauge is off, you can't use the gas gauge to figure fuel milage is my point

LOL that would be MAYBE my MPG unloaded with tail wind in my E350...

I get a rock solid 14 mpg when not towing with my van but it it 10mpg or less, usually closer to 9.0 towing my TT.

I'd like some of that happy smoke your buddy has!

I think he was doing the math on part of a tank of fuel. Does not work. Need at least 1500 miles or so to figure.. However I can get 29 mpg with my Jamboree 23b /7.4 Vortex if I fuel at Pilot in Weed calif and come home down the old 99 highway to Yreka. Its 37 miles and down hill all the way and most times has a stiff breeze behind me and I keep it at 45 -50 mph. Can get 47 mpg in my Subaru Forester.. The rest of the time both get about half of what I get on that trip.

The Ford V-10 is great engine but contrary to popular belief the "10" does not refer to the number of cylinders. It is the mileage that you will never, ever, no how, no way, see regardless of what you are driving/pulling.

2000 Winnebago, Minnie Winnie DL, 29 ft.

Driving the unit home from purchasing in Phoenix, Interstate all the way, cruise set at 65, 8.5 miles per gallon. Maiden voyage to Mission Tejas Park in Texas, 2 and 4 lane roads, not interstate, cruise set at 55 and 60, 8.2 miles per gallon.

Minimal testing of driving around town: 6.7 miles per gallon.

I'll say about this like I said about my Dodge Deisel...I didn't buy it for MPG...I loved my diesel and certainly love the pickup power of the V10 on the road. PRICELESS!!!!
