On a good day, we get around 7.5 towing our Explorer Sport with our Greyhawk. Most of the time, I don't bother to check it, it's just the cost of having fun!

I have a '99 Eagle 283G, 6.8L V10. I average 8.8 mpg. I just replaced the original fuel filter with 61,000 miles. I haven't made another trip yet to see if the fuel usage improves. I don't think anything else will help mileage except keeping the tires fully aired up and minimize total weight of the vehicle as best as I can.

Changing the fuel filter will probably not have any impact on mileage. These motors are EFI - so they self-tune to a specific air/fuel ratio. A clogged filter might make fuel pressure drop - go lean and set a code, but if you were running fine otherwise, it won't make a difference.

Note, I've had 3 V10 RVs. 61k is really really long in the tooth for a fuel filter. It's like driving a Honda 400k miles on the same filter... I've seen them be in really bad shape at way less mileage.

The good news is that they're pretty easy to change with the correct tool.

2012 3100 SS Greyhawk Ford V10. Weighs 13,280 ready to go, including wife and I and full fuel, no water. I drive conservatively and never exceed 60 mph. Towing small pickup that weighs 4,100#. Mileage varies, best 9mpg, worst 7 mpg. Towing the pickup seems to make less difference than I expected, and mpg seems more dependent on severity of wind and hills.

My first summer with a new 2013 Greyhawk I calculated 10 mpg or 23.5 l/100 km for all the Canadian folks.

2004 Escalade V10. 10 mpg. 8.3 towing a 2700 lb boat. With a head wind I lose about 5 mpg. Have Banks systems.

If you want better mileage you have to go smaller. My 4.0 Grand Cherokee towing my 15 ft Sprite Musketeer TT averaged 15 mpg. My Expedition gets 10 mpg towing my JayFeather X213.


Basic physics.

I started to measure my mileage/kms in amount per day.

Softens the blow a bit.

There are many different RVs, with greatly differing fuel economy, and it's smart to ask the question. If you travel less than 5000 miles a year, mpg might not be important at all, but if it's 20,000 miles a year - that'd cost $7600 at 10 mpg. That's significant, and could be the major cost of ownership, especially if it's used RV with modest depreciation.

Another fuel milage thread and the answer is always the same, 8 to 12 mpg depending on vehicle, load, road condition and speed. RV fuel cost is going to be higher than a non-RV but unless its a super lite tent camper, its pretty much always going to be in the 8 - 12 range. But the cost estimate above for an RV of $7600 at 10mph is a misnomer. The net difference between an RV and your TV without an RV or a truck with the same engine package will be less than half that amount since your MPG will maybe go from 18 to 10.

Don't let MPG run you out of RVing. Drive to that resort and stay in a hotel or cabin and add up your cost when you get back home. We don't RV just to save $$ but we often do.
