Gas Mileage Hurricane 32N

I have a 2015 Hurricane 32N with 5500 miles on it and am wondering about the MPG. I'm currently averaging the same with or without a toad (7 - 7.5). Is this close to normal?

That sounds about right. We only get 9 or 10 mpg in our unit (which is a good 10 ft shorter than yours).

The V-10 is a thirsty beast.

My V10 gets 15 MPG at 70 MPH. It's a van though.

It's not that the V10 is inefficient, it's much more about the power it takes to move a huge motorhome.

There is no getting around a motorhome that takes over 100 HP to cruise on the Interstate.

Welcome to the forum!
Our previous 33' coach with V-10 averaged about 7.5 mpg, towing a small car. Probably the same F-53 chassis and engine you have. Keep a close eye on the air filter and the tire pressure, both can lower mpg. I would kick the cruise control off ahead of even small hills, to prevent the gas sucking downshift. (Discussed in a previous thread on this forum.)

P.S. -- Every RV I've driven was very sensitive to speed. One of the best ways to improve fuel economy is to slow down. It won't make 7.5 go to 10 MPG, but it will help.

We have a Hurricane 31S. Two people, dogs and stuff for a week we were getting about 9.5 mpg. Throw on the Jeep and its different. The Jeep has Mud terrain tires which lend to the already not too great Jeep mileage, but thats Jeep and what you expect. Change to normal highway tires the mpg will probably go up some.

The Hurricane with the Jeep toads' fuel economy is 6.5 to 7 mpg dependent on the Hurricane speed. I generally drive the MH about 5 mph below the posted anyway, but not faster than 65. With or without the Jeep toad I found driving 55-60 gives the best highway fuel economy.

Best trip got 9.7 mpg (max speed 60mph). On the last trip after getting the Safe-T-Plus installed the drive felt so much smoother and I did try to "go with the flow" up to 75mph and the overall mileage dropped to 8.5 mpg.

Bottom line: You trade time (speed) for cash (mpg). Once I retire I see the 60mph as more "my speed" .

Your 9.5 MPG is so much higher than the OP's 32N's 7.5 MPG, that it made me curious as to what significant differences there may be.

I found that the slightly longer 32N is built on a 20,500 pound chassis, whereas your 31S is on an 18,000 pound chassis (according to Thor). But a foot longer and a little heavier would never account for that much difference, not when both motorhome have similar shape and size affecting aerodynamics.

However, checking Ford specs, there is a huge difference in "standard" final gearing between the 18,000 and 20,500 pound chassis. I'd bet that makes a significant difference. Obviously other factors like speed, terrain, driving style, etc. affect MPG also.

Chance, I agree driving style comes into play along with using the tow feature. Without a tow I was being more cautious in acceleration. When you are getting passed by a tractor trailer then you know you need to step on it a little more.

I would try to auto shift below 3000 RPM and cruise I think was 1900-2100 RPM. Using the tow feature seems to get a lot higher RPM's on shift up and also the engine braking on downshift increases fuel consumption. I agree with you driving style, terrain, weight, etc can effect economy.

I was mostly referring to the 25% difference between your 4.30 and his 5.38.

At same speed when you cruise at 2,000 RPM he's doing 2,500 RPM, and much more important your engine is working at higher torque, making it more efficient.

Actually, I find it interesting that your 4.30 gearing, when adjusted for tire size, is taller than the much smaller and lighter Axis' 4.10. That shows there is room for Axis improvement.

Not exactly sure when you should use the "tow mode" but I usually use it when accelerating up a steep climb, and for helping to stop or coming down steep grades, can't really say if it affects my mileage though.

You are in the ballpark. Get a ScanGauge or similar instrument that measures MPG, and you will soon find the best speed and best ways to drive the RV, fuel efficiency wise. Even then, don't expect much more mileage than what you are currently getting.

I can hit 10mpg and change when resetting the ScanGauge after achieving highway speeds (highway only), but am closer to 9mpg combined (highway plus city).

I'm at around 15,000lbs or so. Funny thing though, doesn't seem to be much difference when towing a 3,000lb car or not.

5 to 9

Just finished a 4000 mile trip a couple of weeks ago. I got anywhere from 5.5 MPG all the way up to 9.1 with a toad and driving 55 MPH to 65 MPH with bursts of 70 - 75 MPH. This in all types of terrain Mountains and flat land. Interstate and Highway. Good and Bad roads. Ford V-10 362 HP 30 valve ford chassis.

7.2mpg with Hurricane 27K towing 09 Wrangler at about 60 MPH. That is about the best I can do. Could be California gas with alcohol in it.

Some of these reports are making a great case for downsizing.

Seriously though, there is a lot of middle ground between 5.5 and 23 MPG, the best reported MPG I've seen recently for a diesel Class B.

This summer we spent 2 weeks on the road starting from the New Orleans area and went to the Grand Canyon, Hoover Dam, and Las Vegas and returned home. We also made some stops along the way and on the way back. We did not tow our CRV for this trip. Loaded with 4 kids, a dog and 2 adults. My coach was weighed in right at 20K# full of fuel and 1/4 tank fresh for travel water. I averaged anywhere from 5.5 - 7.2 mpg on this trip. When I got into Texas/Louisiana humid heat, I used the Genny to power the roof A/Cs for comfort. I usually drive 5mph less that posted speed limit.

I will say that I was worried once I got into the Mountains, my V10 would struggle up the 8% grades, but It handled it with no issues... in 3rd gear holding 50mph no issues. Probably why I was getting 5.5mpg on those tanks of fuel.
