Re: Does it cost as much as everybody says
It would be extremely difficult to do. It might be possible if you spend your nights in parking lots and truck stops, but you could have a problem when you need to empty tanks. You will be surviving and little more. You won't be able to buy any kind of health insurance on that budget and you will probably need to carry only the minimum in any other kind of insurance as well. Travel will be very limited with fuel prices where they are today. We will travel from Texas to the Pacific Northwest this summer and we are budgeting $1500 just for the fuel to get there.
If you find work along the road to supplement this and live very carefully, it might be possible. If you have only that $700 and do not earn any supplemental income, very few people could even survive on it and if you manage it will not be fun.
