Please who can help me to find the federal law about the RV overnight parking. I need for my blog (I'm italian). Thank you!

I suspect there is no Federal Law on the subject as this would be the area of State Law.

As noted above, parking rules vary state by state and especially town by town. One town might allow it and the town next to it might not. You really need to know the law of the town you are dealing with.
