Most (all?) wind out canopies have a channel in them so you can attach either a 'drive away' awning or a 'fixed' awning.
If you wind out the canopy attached to your MH you can also get a Safari Room which, in effect, fill in the sides to create a room.
By the looks in your photo you may have an extra channel fitted just below the wind out canopy? If so you should be able to attach an awning to that. Most MH's do not have this extra rail probably hence the confusion...
If you are planning on getting a fixed awning to attach to either the wind out canopy or the fixed rail you appear to have, then you will need to check:-
1) The height from the ground to either the channel or fixed rail. MH awning manufacturers tend to do different sizes based on this so make sure to check.
2) That you also have clearance when the habitation door is open so that it doesn't hit the roof (or any poles) of the awning. By their nature awnings slope away from the MH fixing point. Again, the manufacturer can/should advise the minimum required.
In terms of Safari Rooms, the manufacturer of your wind out canopy will make one (Fiamma or Thule generally) or you may be able to get an 'after market' one...but double check it fits your make/model of wind out canopy. We had one and found it very heavy and bulky to carry around...and also a pain to dry at home when wet.
In terms of non drive away awnings there are quite a few to choose from. We have just bought a Kampa Motor Rally Air 260 XXL for our new MH. It is regarded as a 'porch awning' I believe only being 2.6m wide. This still weighs 20kg but does pack down to one bag. We haven't tried it yet so I can't comment on how good it is. There are other makes and ones with metal or fibre glass poles out there...you will need to do your research.
We had a Kampa drive away awning but I sold it as we seldom used it. For us it was too long to fit most pitches and its layout didn't suit us. It was also very 'flappy' in wind!
