We need an address to we could hire!

Hi, my name is Marius and starting with November 23, I'll be in Germany, with my dad at work. We are truck drivers(LKW Fahrer) but for us to be able to hire in Germany we need to have an address(anmeldung). The idea is the following: we being truck drivers we will always be left so that we live in the truck all the time. We don't rent to live there,let's say possibly max 2 days/month or not at all, we need to rent we could hire, for that anmeldung. We can offer max 130 Euros/month.
So we need only an address,without staying there.
We are interested for rentals in Baden-Wurttemberg land.
We are from Roumania, I am 21 years old, my father is 47 years old.
I don't speak German,I speak English and a little of French.
Please e-mail me if you want to help us or for other information/details.
