yea..... definantly not something I want to set any land speed records in.... I was just traveling down a steep hill & wanted a good head start going up the next one.  Felt the thing slow down & make some beeping noises & the computer stated hit speed limiter or something like that. 

I would hope that if a vehicle can travel at 82-3 mph max the tires would be rated for at least that speed.  With cars manufacturers do not throw tires on their vehicles which are rated below what the max speed of the car is.

Nearly all 19.5" and 22.5" tires for RVs  are rated for 75 mph. That's a sustained speed, so you don't need to worry about briefly hitting 80 when passing or going downhill.

Passenger cars rarely have tires rated for anywhere near their maximum speed.  Typically only high performance models will have speed-rated tires on them.  There is a standard classification for tire speed ratings which starts with the letter L (75 mph) and goes up to Y (186 mph). If your tire doesn't have a speed rating stamped into the sidewall, it is probably 75 mph.

Then why was I chewed out by so many forum members here  for going 75 MPH where the speed limit was 75 MPH?

As I recall the thread, you were driving at a sustained 75 mph rather than the brief high speed I alluded to above. And those who castigated you were questioning your judgment in driving a large vehicle that fast, not the capability of your tires. 

I've been known to drive 70-75 myself when highway conditions are suitable and the additional fuel cost is worth the time to be saved. Others will argue that conditions are never suitable for a 15-20 ton vehicle to be moving that fast. Neither side is likely to convince the other to change their mind, so any debate is academic in nature.

Tires were mentioned there too. Now that I took another look at that thread, I see the max speed rating of tires drops as temperature is increased. It was quite warm (If not ridiculously hot <107F, IIRC>, as in Dodge City) during that entire trip.

IFrom the european cars I have owned I have had tires which exceed the car's max speed.  Take my viggen as a example which can do +160 mph, the tires that were on the car were rated above those speeds sustained.... the cars that I own (non-american) are all built for the autobahn so it is likely the car could of seen those speeds thus the appropriate tire.   V or Z rating

The american cars I own are completely lacking in the performance area & are governed to such a speed that a S or H speed rating is all that is needed thus that is the tire on the vehicle.

Want good milage out of your V10?   55MPH will get you the best milage; if the roads have no hills. :)

I've been running the cruise at 61 mph and would get just under 8 mpg. Yesterday we were driving through some heavy rain so I slowed down to 57-59 mph and it went up to 8 1/2. I guess 55 seems to be the sweet spot for this setup.

We have a 2008 coachman freelander 31 ft.   v10 put a k&ncold air intake on it , we get between 8 and 10 mpg,  i think  it made a difference so i guess its worth it , we drive 60 mph to 65mph most of the time unit has 12thousand miles on it so i dont think it is broke in yet,

You guys are making me feel good about my 11.2 MPG (9 to 9.5 towing my Titanium 25' 5er) but what I don't understand is:  I put on a K&N air system = better mileage + 1, then a Gibson exhaust = better mileage +1.5 but sounds like a pregnant bumble bee on steroids, then a Banks performance chip = mileage tanked - 4.  Why??  Ok, the truck does pull better, and I know HP costs gas (energy) but really.  Now I can actually use cruise control pulling in all but the mountains, but - 4 mpg?

Any ideas?

Seems like the bottom line for this motor is small unit ~24' and slow speeds....~55mph gets in excess of 10mpg..... sounds good to me.... :)

Without knowing exactly what the Banks chip does, it is hard to guess why you went -4 mpg. It may well be changing the management parameters enough that you are mostly running in a lower gear (the ECM and transmission interact a lot in a modern drive train).

Is that the Banks Transcommand module that you added? I couldn't find an actual Banks chip for the V10 when I tried to learn more about it.

That is absolutely incorrect. You will get significantly better gas mileage between 50 and 55 mph as opposed to over 60 mph. Wind resistance is the big fuel mileage killer, not weight. And wind resistance increases AT THE SQUARE OF VELOCITY! Slow down and get better fuel mileage.

When we bought our 2006 Fleetwood Storm, Ford V-10 Triton we were told that if you stayed between 61 an 63 miles per hour you would get your best gas mileage. So far it varies between 7 and 10 and I'm very happy, it could be worse. We also pull a toad.

I recently drove My 2017 V10 from Indy to Seattle thru Yellowstone and returned thru Colorado, taking I-70 up and thru the Johnson tunnel. My best mileage 9.5 MPG, was in Yellowstone where speeds are limited to 45mph. Next best was the first day out 9.1mpg leaving Indy and headed to Wisconsin Dells. Worst mileage was in Colorado climbing towards the summit, at 6.8 mpg. I drove with the cruise control set at 65, and dropped it to 55 climbing in Colorado. Overall mpg for entire trip came in at 7.8 mpg.

I have yet to break 8 mpg but I don't blame it on the Ford v10. Simple physics - 31 feet and about 14,000 pounds with the all the aerodynamics of a piece of plywood.  Oh and things hanging off of it like an air conditioner and awning don't help.  Want better mileage?  Drive your Prius and stay in a hotel OR take off what you don't use. 

Lightening the load can make a difference.  Travel with only flushing water, empty black and grey tanks, no EXTRA clothes, do you use the awning - if not leave it etc.  We are doing the maths on renting a car on our next Florida trip - towing eats up the fuel and we are traveling from pennsylvania.

I tried to be a light foot driver and that lasted a tank of gas and the math......I didn't save enough for me to worry about it but my wife and I still work full time so when we travel we have to be back to work.  Don't worry about me speeding - just about impossible for me to get it up and stay AT the speed limit!!

I am not a brand loyal but I don't think the issue is the v10 or any other gas engine - we are simply doing a lot with it and asking a lot of it!

I know this is a V10 thread, but my 8.1 gets about the same. I've put on a little over 3000 miles this summer, and run close to the speed limit, 7.6 is what my 34 ft Dolphin gets. My coach weighs 19600 lbs, and it is tall and wide. My Damon Challenger got much better fuel economy with the 7.4, but it weighed in at 13600 and was much shorter and narrower. Wind resistance has a lot to do with fuel mileage. I didn't buy a motor coach for fuel mileage, but I sure liked the 10/ 11 mpg the Challenger got, compared to this Dolphin. I sure like the extra room and comfort I got with the larger coach though.

figure on 7-8 MPG... if you ever get 10 MPG then you probably made an error in your math.

When we had our 2000 Bounder 36J with a toad (2007 edge) it would average out to 6 ish driving between 62-65.
Yes the v10's are screamers...you think its going to fly apart...but that's where they make the power..

It's all about power to weight ratio...smaller coaches with V10's will most likely get better mileage than larger coaches...also depends on how heavy its loaded and if you're towing something.....

All listed below towing:

Average
65 mph, wind less than 5-10mph, 7.5 mpg in two different class C's and a Class A.

Best ever:
Road construction limited us to 55 mph and we had a tail wind of 35mph, 9.5mpg.

Worst ever:
Raining like a monsoon into a 35 mph headwind, 5.5mpg
