Camping toilet / basic essentials (Mapperley Park NG3)

Hi, I've just found my friend a caravan opposed to him sleeping on the streets.
He needs some kind of basic camping toilet, the type that takes a bag to dispose of rather than a cassette and chemicals.
Also need some gate type hinges to fix the door and other basic essentials like a blanket, battery, USB or rechargeab lights.
Thanks In Advance
