The Portico XL can be fitted like a conventional awning at either end of the van, which is tidier and more stable in wind. On our Indiana we fix it in the front rail, then the vertical padded pole runs down the middle of the little window over the sideboard. Not ideal, but I think it will always be a matter of luck with a porch awning whether you can fit it entirely between windows. You can fit an annexe at either end of teh Portico XL, but I thought them a bit pricey. Instead we got a Sunncamp lightweight which we may (not done it yet) put up on the other side of the van if pitch space permits to provide a bit of extra storage, or just use it nearside for short breaks.
