Awning or not?

Hi All,

We've had our Motorhome for 3 years now & we love it. We're contemplating getting an awning for the coming season but we're wondering what people think of them? Do they get warm in the sun like a conservatory, are they particularly hard to erect, what are the negatives of having an awning. Theres only the 2 of us but we were thinking it'd be nice to have an extra room. Any advice will be gratefully received.
