3 - 9 MPG, depending on the class of RV, powertrain, specs, loaded weight, and terrain.
This depends on the year and mileage of your RV. On average, it costs about $400 a year.
That depends on the RV. Some use diesel fuel, some use gasoline, some even use propane or CNG.
It depends on what type of RV you have. Some motor homes will take diesel, while some others take regular unleaded fuel.
Hybrid cars are not only good for the enviorment but have excellent gas mileage. Anything big like a truck, rv, van or anything like that will have horrible gas mialiage. Also smart cars are great on gas along with a lot of smaller older cars.
Depends on which RV you are referring to. None of them get good mileage.
When I am running empty, I get 11, when I am towing my boat or RV. I get between 7 or 8. WOW, wish I had my old Dodge Cummins back. The V-10 has alot of power, but you pay for it with gas mileage.
No, the mileage will not turn on a car being pulled
It means the engine is in the rear of the bus or RV.
Before setting out on a long road trip, you should verify your vehicle's gas mileage. This is especially true if you are renting an RV or will be pulling a trailer. Vehicles get better gas mileage when driving on the highway. If you will be doing a lot of stop and go driving while on vacation, it will be better to calculate your gas mileage in town. Knowing your fuel efficiency will enable you to develop a more accurate budget for your trip. It will also help to ensure that you do not run out of gas when you are exploring areas off the beaten path.
Yes.
Depends on mileage, options, & condition.
Wow, it really depends on the size of the generator and the particular model. My 7kW RV generator uses about 0.9 gallons per hour at full load. My Father's 3.6kW RV Generator uses about half a gallon per hour.
