Awning for 52 plate Hijet

Forum: 

We are to embark on a small kind of conversion of a 52 plate 1.3 petrol Hijet. We just want to put a fixed bed in (or Rock n Roll, depending on how we feel) with storage underneath. We don't need a sink or a fixed stove - electrics etc as we will literally slum it and be happy with that! BUT we do want an awning for longer trips and we do need some advice about boarding the interior out. Currently it is literally a van with two seats and sliding door etc. Any help and advice re: appropriate awning and battening would be greatfully recieved!
