There is no getting around the gap at the front, you cannot get the side flaps flush with the van. We used our awning for the first time at Beautiful Days last weekend. Overall I am happy with the awning, it's easy to put up and provides a lot of space. My main issue with the awning is the doors. Unless you have the fly screens zipped up the door frames have no rigidity. What you end up with only the door panel closed is a flap at the bottom and every time you undo the door, the bottom flaps in and all the rain runs into the tent. I'm currently drying ours out in the garden and there was a shower earlier. Even with the main front door closed there are only three crappy patches of Velcro to hold the bottom of the door closed. So rain ran off the door, the bottom of the groundsheet fell outside the bottom of the door and a puddle gathered inside the tent. The groundsheet areas below the doors should be higher and of a thicker material. I also don't like the additional groundsheet as water gathers on it underneath the awning groundsheet.
Vango should have made the fixed groundsheet on the awning a little more robust. Unless I have an older model and Vango have addressed this?
