Slower speed and shorter trips are the only two that will make much difference and even they will not make much of a difference. Fuel mileage is what it is and the less you worry about it the more enjoyable your RV experience will be.
Do I like that my coach gets 8 miles per gallon-No. Do we use it less because of that-No.

Hi,
I had air tabs installed. According to my scangauge 2 I get an extra mile per gallon. Cost was $218.00 for parts--or about one tank of fuel where I live.
As a side benefit the RV is quieter inside when I drive.

I hate it but 55 get me 8 plus and 65 get me 7 plus and 70 get me mid 6's.
We drive 2 hours or less to go now, but it is cheaper than airline tickets, rentals, and hotes. Spend the money and enjoy yourself. If your broke, camp close.

Better yet!
Walmart offers a 10 cent discount is you use their "Walmart Credit Card" for gas. This is their incentive to get you to apply for their credit card and all the fees that go with a credit card and the monthly payments, minimum payments, late fees, etc.
What you do is go and buy a Walmart Gift Card and use that to buy gas at their stations and get the discount......stupid pump can't tell the difference and no credit card fees!!  ................................
In South Texas, that only works for a three cent discount.

Wow I'm loving our truck more then ever now...We get up to 14 MPG and average 10-11 MPG of course this changes if we are towing up a grade then it drops down to 9 MPG I'd say this truck is a keeper....My hubby also keeps his speed at 55 and also watches his RPM's

Three sure-fire ways:
(1) Stay home
(2) SLOW DOWN WHEN YOU DO DRIVE
(3) If you don't like #2, see #1

Slowing down is the best bet. From towing a TT, to our present MH, we have managed getting our best fuel mileage between 50-55 mph. Its tough to do it on our short trips because we need to go with the flow of traffic. On our long trips, I now travel during the night. Less traffic and cooler temps helps alot. I aversge a 2 mpg increase doing this. Oh btw, I have a sure fire way of getting a much better increase, but I got beat up here pretty good, so I will have to keep that one a secret 
Full timing it since July 2012 My pics

Agree with others - slow down. This country could put a HUGE dent in oil consumption with better driving habits (if you live in the northeast you'll understand where I'm coming from). The higher the speed the more energy you need to overcome wind resistance. That's simple physics.
I would also check to see how much "stuff" you may be carting along that you don't need. Whenever we prep for a long trip (as opposed to weekends) the first thing I do is go through the TT and jettison anything that won't get used. This includes stuff like extra eating utensils, area rugs, and up to and including - yep - the television. Minimal clothing, little or no water in the freshwater tank. At lower speeds you burn more gas overcoming the inertia and getting all that weight moving. Our lashup tips the scales at 12,000 lbs. We routinely get 11+ mpg traveling and I believe it has everything to do with watching the speed and going light, and less to do with the 4.30 axle ratio on my TV.

Not really. The extra you use going up you save going down. I found that I get slightly better mileage towing in the mountains than on flat land.

I downsized to a travel trailer that I can tow with a Silverado 1500 which gets great mileage when not towing compared to my 2500. About the same, 11 mpg vs 9 mpg when towing.
