I have been reading about what you should expect for fuel mileage. I have noticed a steady drop in MPGs over the years. Like 15 years ago I took my 29.5 foot Coachmen on a long trip and got 9 mpg. Now...
Fuel mileage and RVing in the same sentence...same discussion...NAW.
Doesn't matter what state you get your fuel in. I'm not all that sure about about many things, but I am sure that if you are RVing, you are going to get terrible mileage...count on it.
