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...
Californians will always pay more, in taxes, food, fuel, etc. Just don't go there or live there if you don't like those factors. I am a native Californian and I go there every winter for 3 months, because I still love the state no matter what the cost. Also if you need to worry and analyze every $ spent on your MH you need to find a different way to travel!!!
