Hi, and Welcome to the Great American Roadtrip Forum.

As one who has crisscrossed the 48 States in different directions, numerous times, I have never *planned* such a trip. But to think that you can do it with free camping is a fantasy. For one thing, that website has very very few places where you can actually camp, i.e. set up your tent, leave it for a few days/weeks and stay put or go enjoy the surrounding areas. All too often I have come to one of their sites, and would not dream of leaving any of my belongings. Not like you can in State Parks and Forests, National Forests and other public lands. In reality, this is really only possible in the western States. There are very few possibilties in the eastern and middle States.

Looking for a place to pitch your tent and go fishing, or pick berries or other wild edibles is possible, but not by using that website - or any of the other "free camping" websites. Public lands will give you that possibility, and then I would feel most secure only if I were camping in the company of other campers - not totally alone.

As for doing this all on a moped, is questionable. You have nowhere to secure your valuables. And you will have valuables - no matter how little you take. Water in a hot summer can be more valuable than money. Relying on solar may not be the smartest thing to do on such an extended trip. As much as I have tried solar lights, and have everything running on solar at my home, I am convinced it is not up to the stage of being reliable enough in summer without a backup.... and I don't mean just a butane stove.

I have seen many solar powered tents, with cells all over them for lights and warmth, but I doubt you would get enough to keep perishables (you will have some!) and light your tent.

I would not worry about how much it will cost. I would start first by taking weekend, and then week long trips, and see how you go. Any problems you have then, need to be multiplied several times over for a cross country trip...... especially through the mountains.

I for one will follow your progress closely, as I would love to know how you get on.
