Going Camping What To Bring

What do i need to bring Camping in a RV?
My boyfriend and i are going camping with his family tonight. They’ve already been up there for a week, and we’re just visitting for 2 nights. What should I bring? They have an RV so do i need the basic things like sleeping bag/ pillow ect, or just personal things?
Why not have your BF ask what’s needed, if they have a cell phone it would be simple enough.
