Porch Awning for a Lunar Meteorite

Tinkerbell72

I recently bought a 1992 Lunar Meteorite 2 berth caravan & having had the first outing away in it have decided that I really need to get an awning of some sort.  Need advice on which one to get, guidance say I need to get an awning size of 740cm. Am looking
at porch awnings, I measured the caravan & it is around 210cm high & need awning width of between 170cm & 230cm
