We used our Vango Kela 3 last week at Ullswater. It was quick to set up and drive aways were very easy with the kador strip and figure of 8. That said, we didn't use it quite as much as we expected and, aside for one night when we used it, as we thought we would, for additional outside seating, it became little more than a storage and drying space for our outside tables/chairs and sailing gear. The bit between the closed off awning and van did make a nice undercover cooking area though (the Fiamma wind out with a windbreak would work equally well though).
The footprint worked well and made lining up, both when pitching and for drive away, a lot easier - it covers the whole of the awning not just the closed in area.
The Fiamma roll out did make it easier to set up and put additional tension into the roof of the open part of the awing - we had no issues with the roof or sides flapping and/or slapping the sides of the van. Just roll the FIamma out a couple of inches, attached the awning and then roll the Fiamma back in to tension the awning roof and then use the storm straps to put a bit of tension in between the roof and floor.
In short, we will use again but maybe not until the warmer months and/or when we are sailing (our boat is now stored away in the garage and probably won't be out again until March/April).
Pictures below of awning set up - not perfectly set but, in our defence, it was pouring with rain when we put it up and we couldn't be bothered to redo it!!
