Do we need to buy a drive away awning kit for this model We have an awning rail attached to the van so does it just slide in as I have seen a kit that includes poles

As this driveaway awning has a tunnel section that detaches from the main body, you don't have to buy a fixing kit (to go into a rail). Instead, you can just zip the tunnel section off of the main part of the awning and then unfeed it from your campervan. If you do not have a rail then it would be a good idea to purchase a Pole & Clamp kit (if you are looking to put the awning onto a gutter) to use the throw over guyropes which are supplied with awning.
