That is true, but the additional cost of Diesel must be included in the equation. So the true comparison between gas and Diesel mileage must actually be Cost Per Mile. There are other more intangible factors, but these are debated in all of the gas vs. Diesel chassis threads.

A gallon of diesel weighs 7.15 lbs, a gallon of regular gas weighs 6 to 6.3 lbs per gallon... All things being equal, you get more miles per gallon from diesel

how do I fiqure my milage and how much My coach is using per mile?

If you have a computer it is easy to set up a spreadsheet that will figure all that out for you.

Miles driven in A1 divided by Gal used in A2 = Average in A3
A1/A2 results in A3

I have one that has keep track of all the fuel/miles put in/on my MH since I bought it in 2002.

Average 10.223 MPG
Cost per mile 0.240¢
Cost per Gal. $2.451

grits 58, I was sitting here reading these post and ran across yours... I ran the numbers to see what you were talking about...I was a truck driver for 12 years... a 800 mile trip depends on if summer time, spring.. the reson is let's say it's 90 degrees and you are going to the gennie..don't know if you have one gas tank or two..here are the #. 800 miles @ say averge 60 mhp.=13 hr trip..old gennie is sucking 1 to 1 1/2 gal per hour.. say for old sake 1 1/2... a 13 hr trip =19.5 so the point being when you figure fuel the best way is to fill it up. write down the miles run a 100 mile trip without the gennie running fill it again check your miles .. devide gal into the mile and you will get true miles on your mh..

I have been using a Scanguage D on my MH pretty much the entire time I have owned it. I have done the math every way you can do it and my 330 HP. Cat engine costs about .42 cents a mile to operate. Speeds between 62-68. Never tried anything much slower on a real trip. Now that diesel is over 4.00 a gallon I may need to slow down a bit to keep the costs at or near my target of .40 cents a mile. In the mpg equation, 8.7 to 9.5 mpg with no toad. I control my costs with my right foot. Wind, road conditions all add or subtract to the real costs but you can control that with your right foot. Want to get 10-12 mpg, go 55 and watch the world go by. Cost per mile is what you want to know and be concerned with. MPG is just a number when you are driving you home down the road. Good luck and seeya on the road.

..old gennie is sucking 1 to 1 1/2 gal per hour..

That Gennie needs a tuneup, using that much fuel.
Or is it running 4 roof AC's at the same time?
.5 to .8 GPH is more like most generators use.

It would appear there are more problems than a tune up would cure. How are you (the OP) calculating MPG?

So if anyone can show me the chart on how to do it please help Thanks.

I can promise you this if you put Diesel in your tank you won't be going anywhere.

In the same vein as this discussion, we are also in the midst of this long research for our first MH. One thing I have struggled to get my head around is the lack of information about mileage and its variants. I understand the various factors that impact the mileage (i.e. eleveation changes, weather, toads, weight of personal gear, lead feet) but what about the impact of, let's say, a 30' rig vs a 40' rig. This never seems to be any topics focus. I appreciate that I would much more comfortable in a 36'-40' rig (and I certainly will keep all these other facotrs in mind) but I still want to be aware of all the impacts of my decision. So if a 32' rig and a 38' rig are using similar propulsion options and all else being equal shouldn't there be a mileage difference for each of these? If the difference is truly negligible (which is the primary indication I have receive from salesman and other threads), then are we saying that the 30'-34' rigs are only around for those who are more comfortable manueving the smaller rig and for greater camping spot choices?

Sorry for the long iteration but I have a lot more questions and it will likely only get worse

I just figure $.50 a mile and head out.

X2. A good figure that will not let you down.

I have a diesel pusher, and have been satisfied with the mileage. Terrain is a big factor, wind, and whether or not you are running your generator or not. The biggest thing that helps me is to SLOW DOWN. Sixty mph is fast, and any faster it takes longer to stop. Keeping the rpm low will help, but the terrain is the biggest factor.

Consider the time savings between 55mph and 65mph per 100 miles. I can go about 500 miles in a days driving if I'm desperate. That is about 9 hours at 55 and 7 1/2 hours at 65. The less miles the less savings. What makes that hour and a half worth the extra fuel cost, white knuckles and bored HPs? JMHO...

I am using a computer program called "RoadTripHD" on my iPad. It will track fuel, mileage, maintenance, repair, payments and just about any other item related to your vehicle(s). It will make your eyes bug out so I suggest caution if you're seeking the truth...
