We had similar dilema when we had twin axle van,the answer that worked for us was a smaller full awning.we bought a 950 Ventura,You need to 'break' the bead that fits into the awning channel and invest in a upright pole and pad like the Isabella one.You get a 3/4 size awning that fits in the channel for most of the way round, and is a better fit against the van side than traditional porches.With us it left the barbecue point free at the front of the van and covered from the door near the front, to the rear of the van.To decide on the size you will need,first check where your windows are then measure vertically where you want the awning to end,add to the channel measurement from where the upright pole will be to the ground and away you go.Sounds more complicated than it is, we bought our awning from e bay,never been used.If this is still too big you can buy a smaller awning and use 2 sets of back poles,to create what is in effect an overgrown porch.
