For those of you out there who may be reading this and contemplating a journey of your own across the USA, I thought it might be helpful to give a short rundown of what a trip like this can cost. First, let me start by saying that a trip like this can be done much cheaper than what we did it on. I think hotels in the USA are the greatest expense to most people who travel here.
Camping is the key.
An alternative to tent camping is to stay in a cabin that many larger campgrounds have. The cabins usually have a double bed and a bunk bed with two single beds. They also have elctricity and a nice porch swing. We staying in one in Jackson, WY and loved it. And it was cheaper than a motel room by far.
