Jumuah is not fardh on musafir. If you intend to stay for fifteen days or more at the place where you are going then you shall be muqim there. But if you intend to stay there for fourteen days or less then you shall remain musafir and Jumuah is not fardh on musafir. But if four of you want to establish Jumuah salah together then you can do so, or you can offer it behind any muqim imam if you wish. Jumuah may be established in the city or on its outskirts in places other than mosque also. Mosque is not a condition for Jumuah.
Allah knows Best!
