How much does gas cost to drive to Florida from llinois?

That depends on the mileage of the vehicle you are driving. For example if you are driving a SUV that gets 15 mpg then 1577/15 equals 105 gallons. Just multiply 105 by the cost you pay for gas and you'll know the total cost for one way.

Well gas will not be your largest expense dear. The chances of a small RV making that trip are pretty slim. It has much to do with point A and point B for eample from Tallahassee to Juneau is several hundred miles less than from Key West to Juneau. Meaning if your RV ran 8 miles per gallon $100.00to $200.00 would be the difference. Personally I would not attempt this trip without $5000.00 in reserve on my debit card and a fairly new vehicle. A wiser choice might be to fly in and rent suitable transportation after you get there. Good Luck

Cost of travel = (Total Miles driven / MPG) X Cost per gallon

If you assume $500 for gas - total for the roundtrip you will be pretty close.

ummm no way of knowing unless you post what you drive...a 10 mpg hummer or a 50 mpg yugo....is it a diesel truck? a moped?

Depends on how much gas there is & how big your gas tank is...
