Could be an NR Libra. Not on NR awnings website so probably a discontinued model, plenty of pics if you google, its just a standard caravan awning so goes up much like a frame tent, usually steel poles. Usually made of Tencate which is a good quailty fabric.
Most campsites want you to use a breathable groundsheet to avoid killing the grass, but a cheap plastic tarp will do the job if campsite is not bothered. Awnings ain't normally supplied with groundsheets.
